Expand the integral $\int\left(\sec\left(0.05x\right)-1\right)dx$ into $2$ integrals using the sum rule for integrals, to then solve each integral separately
The integral $\int\sec\left(0.05x\right)dx$ results in: $20\ln\left(\sec\left(0.05x\right)+\tan\left(0.05x\right)\right)$
The integral $\int-1dx$ results in: $-x$
Gather the results of all integrals
As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration $C$
