Question

Q10. If cosecA + cotA=x then cosecA equals to
x²-1
a.
x² - 1
b.
2x
*2+1
x2+1
C.
d.
2x​

Answer 1

• x^2+1/2

co cosec theta + cot theta = 2 X so cos x squared theta minus cot square theta is equals to 1 also cos theta + cot theta into cosec theta minus cot theta equals to 1 so cos 6 theta minus cot theta is equals to 1 by x cos theta minus cot theta + cos theta + cot theta is equals to 1 by X + X 2 cos theta = 2 X square + 1 cos theta equals to X square + 1 by 2
