### Midterms

Function sin cos tan csc sec cot
sinθ = $\sin \theta\$ $\sqrt{1 - \cos^2\theta}$ $\frac{\tan\theta}{\sqrt{1 + \tan^2\theta}}$ $\frac{1}{\csc \theta}$ $\frac{\sqrt{\sec^2 \theta - 1}}{\sec \theta}$ $\frac{1}{\sqrt{1+\cot^2\theta}}$
cosθ = $\sqrt{1 - \sin^2\theta}$ $\cos \theta\$ $\frac{1}{\sqrt{1 + \tan^2 \theta}}$ $\frac{\sqrt{\csc^2\theta - 1}}{\csc \theta}$ $\frac{1}{\sec \theta}$ $\frac{\cot \theta}{\sqrt{1 + \cot^2 \theta}}$
tanθ = $\frac{\sin\theta}{\sqrt{1 - \sin^2\theta}}$ $\frac{\sqrt{1 - \cos^2\theta}}{\cos \theta}$ $\tan \theta\$ $\frac{1}{\sqrt{\csc^2\theta - 1}}$ $\sqrt{\sec^2\theta - 1}$ $\frac{1}{\cot \theta}$
cscθ = ${1 \over \sin \theta}$ ${1 \over \sqrt{1 - \cos^2 \theta}}$ ${\sqrt{1 + \tan^2\theta} \over \tan \theta}$ $\csc \theta\$ ${\sec \theta \over \sqrt{\sec^2\theta - 1}}$ $\sqrt{1 + \cot^2 \theta}$
secθ = ${1 \over \sqrt{1 - \sin^2\theta}}$ ${1 \over \cos \theta}$ $\sqrt{1 + \tan^2\theta}$ ${\csc\theta \over \sqrt{\csc^2\theta - 1}}$ $\sec\theta\$ ${\sqrt{1 + \cot^2\theta} \over \cot \theta}$
cotθ = ${\sqrt{1 - \sin^2\theta} \over \sin \theta}$ ${\cos \theta \over \sqrt{1 - \cos^2\theta}}$ ${1 \over \tan\theta}$ $\sqrt{\csc^2\theta - 1}$ ${1 \over \sqrt{\sec^2\theta - 1}}$ $\cot\theta\$

I’m busy studying for a midterm tomorrow morning. It’s a Teaching College Level Mathematics class. The teacher is interesting and younger than I am. He obtained his Masters a year or two ago. My program director suggested that I take this class to ease myself back into mathematics.

After the exam, I’ve got a numerical analysis laboratory. I start the midterm break afterwards. However, it’s going to be a busy time. Coming back from the break, I’ll have three more midterms within two weeks, three homework to give in (big ones involving a lot of coding).

I’m really enjoying the time here. I’ve really gotten into mathematics again. I’ve got a lot to do in numerical analysis and numerical linear algebra. Both classes involve coding in MATLAB.

My teaching hours are most probably going be at around 14 starting next week. That’s almost as much as I wanted. It’s been rough, but I managed to get by. Next semester, I want the least amount of distractions while I study.
