Question

If 5sin-12cos = 0 , find the values of sec and cosec.​

Answer 1

Step-by-step explanation:

5sin-12cos = 0

5sin=12cos

sin/cos = 12/5

tan= 12/5

tan=12/5

on squareing both side

tan²= 144/25

adding 1 both side

1+tan²= 144/25+1

sec²= 169/25

sec= 13/5

again tan= 12/5 then cot= 5/12

cot = 5/12

on squareing both side

cot²= 25/144

on adding 1 both side

1+cot²= 25/144+1

cosec²= 169/144

cosec= 13/12
