Question

If sinA = 4/5 then (cot A + Cosec A) is

Answer 1

Step-by-step explanation:

method 1

If sinA = 4/5

If sinA = 4/5By Pythagorean theorem,

If sinA = 4/5By Pythagorean theorem,cosA = 3/5

If sinA = 4/5By Pythagorean theorem,cosA = 3/5=> cotA = 3/4 and cosecA = 5/4

If sinA = 4/5By Pythagorean theorem,cosA = 3/5=> cotA = 3/4 and cosecA = 5/4=> cotA + cosecA = (3+5)/4 = 8/4 = 2
