How to simplify sin 3x

WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. WebThe formula for the trigonometric function sin3x is given by, sin3x = 3 sin x - 4 sin^3x which can be written as sin3x = 3 sin x - 4 sin 3 x. Now, we will draw the graph of the …

WebProve that sin 3 (3x) = (1/2) [sin (3x)] [1 – cos (3x)]. Solution. Since the trigonometric function is raised to the third power, there will be one quantity of square power. Rearrange the expression and multiply one square power to a single power. sin 3 (3x) = [sin (3x)] [sin 2 (3x)] Substitute the power-reduction formula to the obtained ... WebWe can simplify it further to cos ( 3 x). Indeed, ( cos x + i sin x) 3 = ( e i x) 3 = e 3 i x = cos 3 x + i sin 3 x and the result follows by comparing the real component of the left and right sides.

Here is an example: Websin 4 ( x) = 3 8 − cos ( 2 x) 2 + cos ( 4 x) 8 3 − 4 cos ( 2 x) + cos ( 4 x) 8. I have just applied the Pythagorean theorem ( sin 2 z + cos 2 z = 1) and twice the cosine duplication formula ( cos ( 2 z) = 2 cos 2 z − 1, giving cos 2 ( z) = 1 + cos ( 2 z) 2 ).
