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
