Question

if x = a cosecA and y = b cotA then prove that x square/a square -y square/b square = 1

Answer 1

Answer:hello

Step-by-step explanation:

Answer 2

Step-by-step explanation:

given

x= a cosecA and y=b cotA

now

x^2/a^2 - y^2/b^2

= a^2 cosec^2A/a^2 - b^2cot^2A/b^2

= 1/sin^2A - cos^2A/sin^2A

= (1-cos^2A)/sin^2A

= sin^2A/sin^2A

= 1

hence proved
