Find derivative of given function:

$y}^{\prime}{=}^{1}{\left(5{x}^{3}\right)}^{\prime}+{\left(7{x}^{2}\right)}^{\prime}-{\left(3x\right)}^{\prime}+{1}^{\prime$

${=}^{2}5\dot{3}{x}^{2}+7\dot{2}x-3\dot{1}+0$

$=15{x}^{2}+14x-3$

Rules used:

(1) Derivative of sum

(2) Power rule

Simplify Trig Identity in $\mathrm{sin}\theta$ and/or $\mathrm{cos}\theta$

I just need to simplify in terms of $\mathrm{sin}\theta$ and/or $\mathrm{cos}\theta$

I did this one earlier today but forgot how I did it. I just need help on the other two.

$\frac{\mathrm{cos}\theta}{\mathrm{sin}\theta}+\frac{1}{\mathrm{cos}\theta}=\frac{{\mathrm{cos}}^{2}\theta +\mathrm{sin}\theta}{\mathrm{sin}\theta \mathrm{cos}\theta}$

Question 1: $\mathrm{sin}\theta +\frac{1}{\mathrm{cos}\theta}$

Question 2: $\frac{\mathrm{sin}\theta}{\mathrm{cos}\theta}+\frac{1}{\mathrm{sin}\theta}$
