Chapter  3 Trigonometric Functions Exercise   3.2

Find the values of other five trigonometric functions if x lies in second quadrant.

In second quadrant sine and cosine are positive rest are negative.

sinx=3/5

cosx=-4/5

tanx=-3/4

cosecx=5/3

secx=-5/4

cotx=-4/3


Find the values of other five trigonometric functions if x lies in third quadrant.

Since x lies in the 3rd quadrant, the value of sin x will be negative.
