Expand the Trigonometric Expression sin (4x) | Mathway
Apply the sine double - angle identity. Multiply 2 2 by 2 2. Use the double - angle identity to transform cos(2x) cos (2 x) to 2cos2(x)−1 2 cos 2 (x) - 1. Apply the distributive property. Multiply cos(x) cos (x) by cos2 (x) cos 2 (x) by adding the exponents. Tap for more steps...
How to simplify $\\sin^4 (x)$? - Mathematics Stack Exchange
Folks, how can $\sin^4 (x)$ be simplified to a trig function with power of 1? I tried: $ (\sin^2 (x))^2 = ( (1-\cos2x)/2)^2$ but still getting $\cos x$ to the power of $2$.
How to find the value of sin4x, cos4x, cot4x? - Cuemath
How to find the value of sin4x, cos4x, cot4x? The value of sin4x, cos4x and cot4x can be found out by using the basic trigonometric formulas. We will use the basic trigonometric formulas to find the values of sin4x, cos4x, and cot4x. Solution: sin 4x = sin2 (2x) We know that, sin 2x = 2 sinx cosx Thus, sin2 (2x) = 2 sin2x cos2x = 2 (2 sinx cosx ...

How do you write sin (4x) in terms of sin (x)? Thank you! - Socratic
2017年9月24日 · sin4x = 2sin2xcos2x. = 2 × 2sinxcosx × (1 − 2sin2x. = 4sinxcosx − 8sin3xcosx. This is generally used expansion for sin4x, however to write in terms of pure sinx, one can substitute cosx with √1 −sin2x, although there could be issues regarding choosing appropriate sign based on which quadrant x falls.
