How do I calculate the integral of 1/cosx -sinx? The easiest way to perform this sum would be to multiply and divide by square root of 2 in denominator to convert it to a term of sin function. Another way,probably the longest one,would be to use the half angle tangent formula and then substituting tan x/2 for t. How do you prove the integral formula #intdx/(sqrt(x^2+a^2)) = ln(x+sqrt(x^2+a^2))+ C# ?

=cosx - 2/3cos^3x + C Use the identity cos(2x) = 1 - 2sin^2x. =int(1 - 2sin^2x)sinxdx Multiply out. =int(sinx - 2sin^3x)dx Separate using int(a + b)dx = intadx + intbdx =int(sinx)dx - int(2sin^3x)dx The antiderivative of sinx is -cosx. Use the property of integrals that int(Cf(x))dx = Cintf(x) where C is a constant. Note that sin^3x can be factored as sin^2x(sinx), which can in turn be written

2016-02-10 2014-08-17 The function $\sin(x)\cos(x)$ is one of the easiest functions to integrate. All you need to do is to use a simple substitution $u = \sin(x)$, i.e. $\frac{du}{dx} = \cos(x)$, or $dx = du/\cos(x)$, which leads to $$ ∫ \sin(x)\cos(x)\,dx = \l.∫ u\,du\r|_{u = \sin(x)} = \frac{u^2}2 + C = \frac12 \sin^2(x)+C\,. $$ Get the answer to Integral of cos(x)sin(x) with the Cymath math problem solver - a free math equation solver and math solving app for calculus and algebra.
