integral of cos(θ)tan(θ)

\int cos (θ) tan (θ) d θ

- cos (θ) + C

Solution steps

\int cos (θ) tan (θ) d θ

Express with sin, cos

= \int sin (θ) d θ

Use the common integral:

\int sin (θ) d θ = - cos (θ)

= - cos (θ)

Add a constant to the solution

= - cos (θ) + C

\int (2 x y^{2} - y^{3}) d x

\int 60 (1 + x^{2}) (7 + 15 x + 5 x^{3})^{12} d x

\int 10 e^{t} - t e^{t} + 1 d t

\int \frac{1}{( x + 9 ) ^{2}} d x

\int \frac{1}{1 - 25 t ^{2}} d t
