Notice that this is "sin squared x" and 3 * "cos squared x" $\sin^2x = 3\cos^2x$ //Just rewriting the equation again. $1-\cos^2x = 3\cos^2x$ //Using the Pythagorean identities to substitute in for $\sin^2x$ I then add $\cos^2x$ to both sides yielding: $$1 = 4\cos^2x$$ I then divide by $4$ yielding: \frac 1 4 = \cos… 2018-02-26 Integral of sin(x)cos^2(x) & Integral of sin^2(x)cos(x) - How to integrate it step by step using the substitution method! Youtube: https: Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. The answer is = 1 2 0 1 Explanation: Apply cos 2 x = 1 − sin 2 x Calculate the indefinite integral first Therefore, The integral is I = ∫ sin 7 x cos 5 x d x = ∫ cos x sin 7 x (1 − sin 2 x) 2 d x = cos(x) - 4sin 2 (x)cos(x) Note that in line 3, a different formula could be used for cos(2x), but looking ahead you can see that this will work best for solving the equation, since sin(x)cos(x… Note that tan 2 x = c o s 2 x s i n 2 x is undefined when cos 2 x = 0, i.e., when x = π / 4 + k π, so it cannot be a solution to either the original or factored equation.
