integral of cos(x)cos(y)

\int cos (x) cos (y) d x

cos (y) sin (x) + C

Solution steps

\int cos (x) cos (y) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= cos (y) \cdot \int cos (x) d x

Use the common integral:

\int cos (x) d x = sin (x)

= cos (y) sin (x)

Add a constant to the solution

= cos (y) sin (x) + C

\int \frac{1}{x ^{14}} d x

\int (5 x + 2)^{2} d x

\int_{0}^{1} 2 π x (x - x^{2}) d x

y^{^{''}} + 10 y = 0, y (0) = 2, y^{^{'}} (0) = 10

\int tan^{7} (x) sec^{17} (x) d x
