I used Wolfram Alpha to get the answer but this is what I could get : $$ 4\cos^3\theta\sin\theta- 4\cos\theta \sin^3\theta $$ To simplify the expression cos 4 x+sin 4 x, we first apply the formula a 2 +b 2 = (a+b) 2 -2ab with a = cos 2 x and b = sin 2 x. In my book only the exact $4$ values of trig functions are used when evaluating them, so after solving the above expression in the following way: $$\sin^4(\alpha)+\cos^4(\alpha)=(\sin^2(\alpha)+\cos^2(\alpha))^2-2\sin^2(\alpha)\cos^2(\alpha)=1-\sin^2(2\alpha),$$ I wrote let $\alpha$ equal $90^\circ$ $(\alpha=90^\circ),$ therefore $$1-\sin^2(2\alpha)=1-\sin^2(180^\circ)=1-0=1,$$ afterwards The double-angle formulas are a special case of the sum formulas, where α = β α = β .The right-angled triangle definition of trigonometric functions is most often how they are introduced, followed by their definitions in terms of Solve your math problems using our free math solver with step-by-step solutions.
