**cos3x + 3.** **cosx/4**), Ans.

The derivative of sin3x is equal to **3cos3x**.

Solution: The derivative of cos 2x is **-2 sin 2x**.

**No, cos(x)^3 means the cos of the angle is triple or multiplied by itself 3 times**. If x = 2, then x^3 = 8. This is called exponentiation.

The derivative of the cosine function is written as (cos x)’ = **-sin x**, that is, the derivative of cos x is -sin x.

The derivative of sin 2x is **2 cos 2x**. We write this mathematically as d/dx (sin 2x) = 2 cos 2x (or) (sin 2x)’ = 2 cos 2x.

Sin 3x = **Sin (2x + x)**

The derivative of sin x is denoted by **d/dx (sin x) = cos x**. The other way to represent the sine function is (sin x)’ = cos x.

Since 2 is constant with respect to x, the derivative of 2sin(2x) 2 sin ( 2 x ) with respect to x is **2ddx[sin(2x)] 2 d d x [ sin ( 2 x ) ]** .

Antworten. Also cos3A= **−3cosA+4cos ^{3}A**.

Trigonometry examples

The range is **−1≤y≤1** – 1 ≤ y ≤ 1 .

Therefore cos3(−x)=cos(−x)cos(−x)cos(−x)=cosxcosxcosx=cos3x (i.e. **cos3x must be an even function**).
