Question

If sin A = ½ then find the value of cos A . cosec A + tan A . sec A ​

Answer 1

Answer:

(3root3+2)/3

Step-by-step explanation:

sin A = 1/2

sin 30 = 1/2

so A = 30 degrees

cos A = cos 30 = root3 / 2

cosec A = 1/sin A = 1/ 1/2 = 2

tan A = tan 30 = 1 / root3

sec A = 1/ cos A = 1/ root3/2 = 2/root3

so,

cos A . cosec A + tan A . sec A ​= root3 + 2/3

= 3root3+2
