**How to find the exact value of sin(2x) if sinx YouTube**

9/04/2012 · Best Answer: Hi. You have to keep in mind the this is a composite function, it is composed of sin x and 2x. That is the important thing to remember regarding the trig functions. By using the chain rule you get: (d/dx) sin 2x = cos 2x * (d/dx) 2x = 2*cos 2x Hope this helped.... Question: Find the value of cos(2x) if sin(x) = 5/13 and x is in Quadrant II. Explain why cos(2x) > 0 although cos(x) < 0 in Quadrant II. Double Angle Formulas:

**what is another way to write sin(4x)? Yahoo Answers**

Sin Squared The graph of ( ()) The frequency is doubled. (we have more complete cycles in the same x distance. The phase is... well we could argue that the phase is changed, but it really only makes sense to compare the phase of two waves of the same frequency, so it is hard to say what has happened to the phase. Cos Squared . The graph below does the same thing for Once again, this...

**What is the derivative of [math]f(x) = x^2\sin(x)[/math**

As you can see, this function includes the product of two terms x^2 and sin(x). The product rule states: f'(x) * g(x) + f(x) * g'(x) <- This means we take the derivative of … how to end my period now In Calculus, angles are measured in radians. If x is not measured in radians, this limit will not be 1. This limit says that as x gets small the ratio of sin(x) to x approaches 1. If the ratio of two numbers is close to 1, then the two numbers are about equal. Thus for small values of x, sin(x) is

**trigonometry What is $\sin^2(x)$ equal to? - Mathematics**

In this case, sin(x) is the inner function that is composed as part of the sin^2(x). To look at it another way, let's denote u=sin(x) so that u^2=sin^2(x). Do you notice how the composite function works here? The outer function of u^2 squares the inner function of u=sin(x). Don't let the u confuse you, it's just to show you how one function is a composite of the other. Once you understand this how to find the key for microsoft office Questions 1: Find the exact value of sin (x / 2) if sin (x) = 1 / 4 and x is such that Pi / 2< x < Pi.

## How To Find What Sin 2 X Is

Now, since we know that sin( ) = x, the trick is to draw the easiest right triangle you can think of with the property that sin( ) = x. First, let’s draw a right triangle ABC.

- The function y = (sin x) ^2 is defined whenever sin x is defined, and its values are the squares of the values of sin x. The domain of the function is the set of all real numbers.
