y = cos(x) and the x-axis. Between 0 and π π the amount of area above the axis equals the amount below the axis, so cos(x) dx = 0 0 We conclude that: π sin(x) + cos(x) dx = 2. 0 b) Find antiderivatives of sin(x) and cos(x). Check your work. The derivative of sin x is cos x, so sin(x) is an antiderivative of cos(x). The derivative of cos x is

This does not affect the Feb 10, 2016 Integral of cos(x)/sin(x) - How to integrate it step by step using the substitution method!▻ Youtube: The Weierstrass substitution is very useful for integrals involving a simple rational expression in sinx and/or cosx in the denominator. To calculate an integral of the Jan 7, 2013 Hint: sin(x)+cos(x) = sqrt(2)sin(x+pi/4), and integral of 1/sin(x) = ln(|sin(x/2)| Int dx/(sinx+cosx)= Int (cosx-Sinx)dx/(Cos2x-sin2x)= Int cosx dx/ expression. If we can integrate this new function of u, then the antiderivative of the -x2 cos x + 2x sinx + 2 cosx + ∫ 0 dx = -x2 cos x + 2x sin x + 2 cos x + C. x dx = ln|x| + C. ∫ cosxdx = sinx + C;. ∫ sinxdx = −cosx + C 1.2 Trigonometric Integrals.
