integral of 6csc^2(t)-9e^t

\int 6 csc^{2} (t) - 9 e^{t} d t

- 6 cot (t) - 9 e^{t} + C

Solution steps

\int 6 csc^{2} (t) - 9 e^{t} d t

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 6 csc^{2} (t) d t - \int 9 e^{t} d t

\int 6 csc^{2} (t) d t = - 6 cot (t)

\int 9 e^{t} d t = 9 e^{t}

= - 6 cot (t) - 9 e^{t}

Add a constant to the solution

= - 6 cot (t) - 9 e^{t} + C

\int \frac{- 6}{e ^{2 x}} d x

\int e^{0.6931 x} d x

\int x^{3} (e^{x^{2}}) d x

\int \frac{A}{M A - A ^{2}}

\int 4 arctan (2 x) d x
