Chapter 4 - Integrals - 4.5 The Substitution Rule - 4.5 Exercises - Page 346: 15


$\frac{sin(1+5t)}{5} +C$

Work Step by Step

Evaluate the Integral using substitution: $\int cos(1+5t)dt$ Substitution Rule: $\int f(g(x))g’(x)dx = \int f(u)du$ $u= 1+5t$ $du =5$ Since $du$ in the expression is equal to $1$ it must be multiplied by $\frac{1}{5}$ Solve the integral in terms of $u$: $\int cos(u)(\frac15)du$ $\frac{1}{5}\int cos(u)du $ $\frac{1}{5}sin(u) +C$ $\frac{sin(u)}{5} + C$ Substitute for $u$: $\frac{sin(1+5t)}{5} +C$
