Question

Evaluate(i) sin30° + tan45º - cosec60°
cot45° + cos60° - sec30° -​

Answer 1

Answer:

3

Step-by-step explanation:

sin 30 degree = 1/2

tan 45 degree = 1

consec = 1/sin = 1 / sin 60 = 2/root 3

cot = 1/ tan = 1

cos 60 degree = 1/2

sec = 1/ cos = 2 / root 3

1/2 + 1 - 2/ root 3 + 1 + 1/2 - 2/ root 3

= 3
