Question

if X=a sinB and y=b tanB .. find value of a²/x² -b²/y²​

Answer 1

Answer:

Ans is 1.

Step-by-step explanation:

X=asinB

or, sinB=X/a

or, cosecB=a/X

cotA=b/Y

Now

(a/x)2-(b/Y)2

or, cosec^2B-cot^2B

or, 1

Answer 2

Answer:

1

Step-by-step explanation:

As given,

x= a sinB & y= b tanB (1)

So from the question,

We have,

a²/x² - b²/y² (2)

Hence,

From equations 1&2,

we get,

a²/x² - b²/y² = 1
