Find the exact values below If applicable tap on UndefinedSo

Find the exact values below. If applicable, tap on \"Undefined\".

Solution

csc(-270) = 1/sin(-270) = -1/sin270

sin270 = sin(180 +90) = - sin 90

= -1

So, csc(-270) = -1/-1 = 1

cot(-270) = 1/tan(-270) = -1/tan270

= -1/tan(180+90)

= -1/tan90

= 0

So, cot(-270) = 0
