Step-by-step explanation:
It helps a lot to draw a triangle. Sin is OPPOSITE/ HYPOTENUSE. You can use Pythagorean thm to find the third side. Then use cos = ADJ/HYP
tan = OPP/HYP
Then, find reciprocal functions. Reciprocal just means you are flipping the ratios over.
csc = HYP/OPP
sec = HYP/ADJ
tan = ADJ/OPP
The only tricky remaining part is that you cant leave a radical (the square root symbol) on the bottom of a ratio. So you have to fix those. See image.
