\int ar\cos(x)\mathrm{d}x
Evaluate the indefinite integral first.
ar\int \cos(x)\mathrm{d}x
Factor out the constant using \int af\left(x\right)\mathrm{d}x=a\int f\left(x\right)\mathrm{d}x.
ar\sin(x)
Use \int \cos(a)\mathrm{d}a=\sin(a) from the table of common integrals to obtain the result.
ar\sin(1)-ar\sin(0)
The definite integral is the antiderivative of the expression evaluated at the upper limit of integration minus the antiderivative evaluated at the lower limit of integration.
ar\sin(1)
Simplify.
