How do you remember Sin Cos Tan graphs?
Hello,Pierre learnt trig 2 years ago. But he still remembers the trig graphs thanks to these tricks. Sin: Remember sine by how you say it. S-ai-n. Cos: Remember cosine by its name. Half of it is sine. Tan: It goes up. But the best way to remember is to practice.Thank You.-Pierre.

How do you draw a sine graph?
How to Graph a Sine FunctionFind the values for domain and range. No matter what you put into the sine function, you get an answer as output, because. Calculate the graph’s x-intercepts. When you graph lines in algebra, the x-intercepts occur when y = 0. Calculate the graph’s maximum and minimum points. Sketch the graph of the function.

What does a sine graph look like?
To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called ‘sinusoidal’ after the name of the sine function.
At what angle is sin?
The related angle is 60°.120° is in the second quadrant,so sin 120°= sin 60°= .
What is the formula for a sine wave?
Sine Wave. A general form of a sinusoidal wave is y(x,t)=Asin(kx−ωt+ϕ) y ( x , t ) = A sin ( kx − ω t + ϕ ) , where A is the amplitude of the wave, ω is the wave’s angular frequency, k is the wavenumber, and ϕ is the phase of the sine wave given in radians.
What is the equation of sine?
An investigation of y = a sin (bx+c) for different values of a, b, and c. The graphs of functions defined by y = sin x are called sine waves or sinusoidal waves. Notice that the graph repeats itself as it moves along the x-axis.
What is sin equal to?
They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin(θ) = Opposite / Hypotenuse.
What does a cos graph look like?
To graph the cosine function, we mark the angle along the horizontal x axis, and for each angle, we put the cosine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. As you do so, the point on the graph moves to correspond with the angle and its cosine.
How do you tell if a graph is sine or cosine?
In a cosine graph, a positive or negative number vertically flips the graph and determines whether the graph starts at the maximum (if it’s positive) or minimum (if it’s negative). For a sine graph, a positive or negative number vertically flips the graph like it does with a cosine graph.
How do you go from sin to cos?
The Basic Two: Sine and Cosine(1) Memorize: sine = (opposite side) / hypotenuse. (2) sin A = cos(90° − A) or cos(π/2 − A) cos A = sin(90° − A) or sin(π/2 − A)(3) Memorize: (4) tangent = (opposite side) / (adjacent side)(5) Memorize: (6) tan A = cot(90° − A) or cot(π/2 − A) (7) sec A = csc(90° − A) or csc(π/2 − A)
Where does Cos start on a graph?
Cosine is just like Sine, but it starts at 1 and heads down until π radians (180°) and then heads up again.
How often does tan repeat?
What is the value of sin cos and tan?
Example: what are the sine, cosine and tangent of 30° ?Sinesin(30°) = 1 / 2 = 0.5Cosinecos(30°) = 1.732 / 2 = 0.866…Tangenttan(30°) = 1 / 1.732 = 0.577…
What is the maximum value of sin 3 Theta?
Therefore considering sin3θcos2θ+cos3θsin2θ or sin(5θ) will be the same. So the maximum value of sin(5θ) is 1. As the maximum value of sin function is 1.
What is the maximum value of tan?
The maximum value of tanx is ∞. The minimum value of tanx is −∞. The value of tanx is undefined at x = 90° and x = 270°.
What is the minimum and maximum value of sin theta?
Maximum value of sin θ is 1 when θ = 90 ˚. Minimum value of sin θ is –1 when θ = 270 ˚. So, the range of values of sin θ is –1 ≤ sin θ ≤ 1. As the point θ moves round the unit circle in either the clockwise or anticlockwise direction, the sine curve above repeats itself for every interval of 360˚.
What is the minimum and maximum value of tan theta?
tan θ does not have any maximum or minimum values. tan θ = 1 when θ = 45 ˚ and 225˚ . the maximum value of tan theta is infinity. tan θ does not have any maximum or minimum values.
