Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Although the expression sin 2 x contains no parenthesis, we can still view it as a composite function (a function of a function).

so that sin2x = 2 sin x cos x. And this is how our first double-angle formula, so called because we are doubling the angle (as in 2A). Practice Example for

This can be done using integration by parts: u = x. du = dx. dv = sin(2x) dx. v = -1/2 * cos(2x) (you should be able to get this via a simple substitution) It is indeed true that sin 2 (x) = 1 − cos 2 (x) and that sin 2 (x) = 2 1 − c o s (2 x) . How do you use the half-angle identities to find all solutions on the interval [0,2pi) for the equation \displaystyle{{\sin}^{{2}}{x}}={{\cos}^{{2}}{\left(\frac{{x}}{{2}}\right)}} ?
