Question

In each of the following, one of the six trignometric ratio is given find the value of otherr trignometric ratio
sin a =2/3

Answer 1

Step-by-step explanation:

sin a=2/3

sin a = P/H

P=2

H=3

B=?

H²=P²+B²

3²=2²+B²

B²=9-4

B²=5

B=√5

cos a=B/H

cos a= √5/3

tan a= P/B

tan a=2/√5

cot a= B/P

cot a=√5/2

cosec a= H/P

cosec a= 3/2

sec a=H/B

sec a= 3/√5
