Find the indefinite integral 23tan5θsec7θdθ.\displaystyle \int{23\tan^5 \theta \sec^7 \theta}d\theta.

If f(θ)=sin3θcos3θsinθcosθdθ+(1sinθcosθ)dθ f(\theta) = \int \frac{\sin^3 \theta - \cos^3 \theta}{\sin \theta - \cos \theta} d\theta + \int (1- \sin \theta \cos \theta) d\theta and f(0)=10,f(0) = 10, what is the value of f(30)?f(30)?
