Answer:

I hope it is helpful.............

Answer 2

$\textbf{Trigonometry Formulas:}$

• sinØ = P/H

• cosØ = B/H

• tanØ = P/B

• cosecØ = H/P

• secØ = H/B

• cotØ = B/P

____________________________

» sin²Ø + cos²Ø = 1

› sin²Ø = 1 - cos²Ø

› cos²Ø = 1 - sin²Ø

» 1 + cot²Ø = cosec²Ø

› cot²Ø = cosec²Ø - 1

› cosec²Ø - cot²Ø = 1

» 1 + tan²Ø = sec²Ø

› tan²Ø = sec²Ø - 1

› sec²Ø - tan²Ø = 1

____________________________

• sinØ = 1/cosecØ

coecØ = 1/sinØ

• cosØ = 1/secØ

secØ = 1/cosØ

• tanØ = 1/cotØ

cotØ = 1/tanØ
