limit as t approaches 1 of cos(pit)

t \to 1 lim (cos (π t))

- 1

Solution steps

t \to 1 lim (cos (π t))

Plug in the value

t = 1

= cos (π 1)

Simplify

cos (π 1) : - 1

= - 1

y = x^{3}, y = 4 + 2 x, x = 0

y = ln (3 x) + x

\int \frac{sin ( 2 x )}{26 + cos ^{2} ( x )} d x

\int \frac{3 x ^{2} + x + 4}{x ^{3} + x} d x

n = 1 \sum \infty \frac{1}{n ^{2} + 3 n}
