How do you find all solutions for sin2x=cosx for the interval [0,2π]? How do you find all solutions for 4sinθcosθ=√3 for the interval [0,2π]? Apr 24, 2022 ... Tan2x is a double angle identity. Because the tangent function is a ratio of the sine and cosine functions, it may also be represented as tan2x = sin 2x/cos 2x. Problem. How many solutions does the equation $\tan(2x)=\cos(\tfrac{x}{ have on the interval $[0,2\pi]?$. $\textbf{(A)}\ 1\qquad\textbf{( ...
