Question

x=3cosecA+4cotA , y=4cosecA-3cotA then eliminate A​

Answer 1

Answer:

X =3cosecA+4cotA --------- eq (1)

Y = 4cosecA-3cotA ----------eq(2)

multiply equation (1) by 4.

4x = 12cosec A + 16cotA ----------eq (3)

multiply equation (2) by 3 .

3Y = 12cosecA - 9cotA --------------eq (4)

now subtracting eq (4) from eq (3) ...

we are getting ,,,

4x- 3y = 16cotA -(-9cotA)

4x-3y = 25 cot A

now see the attachment ...

( your answer is 625.. )
