WebSolution: To find the integral of cos4x cos3x, we will use the formula cos A cos B = (1/2) [cos (A + B) + cos (A - B)]. Here A = 4x and B = 3x. So, we have cos4x cos3x = (1/2) [cos (4x + 3x) + cos (4x - 3x)] = (1/2) [cos 7x + cos x]. So, the required integral is given by, ∫ cos4x cos3x dx = ∫ (1/2) [cos 7x + cos x] dx WebTrigonometric Simplification Calculator Simplify trigonometric expressions to their simplest form step-by-step full pad » Examples Related Symbolab blog posts Spinning The Unit Circle (Evaluating Trig Functions ) If you’ve ever taken a ferris wheel ride then you know about … Evaluate Functions - Trigonometric Simplification Calculator - Symbolab simplify\:\frac{2}{3}-\frac{3}{2}+\frac{1}{4} x+2y=2x-5,\:x-y=3; Frequently Asked … Identities - Trigonometric Simplification Calculator - Symbolab Trig Inequalities - Trigonometric Simplification Calculator - Symbolab
