Question

write the formulaes of trigonometry

Answer 1

sin A=a/c = opp side/hypotenuse

cos A=b/c = adjacent side/hypotenuse

tan A=a/b = opp side/adjacent side

cosec A = c/a = 1/sin A

sec A =c/b = 1/cos A

cot A=b/a = 1/tan A

Answer 2

sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
