Answer 2

Please go through the formulas given below

Sin∅ = Opposite side / Hypoteneus

Cos∅ = Adjacent side / Hypoteneus

Tan∅ = Opposite side / Adjacent side

Cosec∅ = Hypoteneus / Opposite side

Sec∅ =  Hypoteneus / Adjacent side

Tan∅ = Adjacent side / Opposite side

Sin²∅ + cos²∅=1

tan²∅ + 1 = sec²∅

cot²∅ + 1= cosec²∅

Sin∅ = 1/cosec∅

cos∅=1/sec∅

tan∅=1/cot∅
