How to simplify 1 - Cos[2x] to 2 Sin[x]^2? Ask Question 5. 1. I LeafCount /@ {Cos[2 x], 1 - Sin[x]^2} (* {4, 8} *) TreeForm /@ {Cos[2 x], 1 - Sin[x]^2} // GraphicsRow The basic built-in function for performing the sort transformation the OP desires is TrigExpand. But TrigExpand applies a different identity to Cos[2 x] than the desired one: TrigExpand[Cos[2 x]] (* Cos[x]^2 - Sin[x]^2 how to wear thai wrap pants An equation such as 2 sin x − 1 = 0 is an example of a linear trigonometric equation, since putting a = sin x produces the linear equation 2 a − 1 = 0. Equations such as these generally have infinitely many solutions, but in practice we often restrict the range of solutions to be between 0° and 360°, or for example between −180° and 180°. We can solve this equation by firstly making

9/01/2019 · I don't think there is an analytical way to solve this. $2+9$: We have $$16^{\sin^2x} = 2\iff \sin^2x = \frac14\\81^{\cos^2x} = 9\iff \cos^2x = \frac12$$ Knowing that $\sin^2x + \cos^2x = 1$, we see that this one is impossible; $8 + 3$: This time we get $$ 16^{\sin^2 x} = 8\iff \sin^2x = \frac34\\81^ {\cos^2x} = 3\iff \cos^2x = \frac14 $$ This one is possible.
