Question

If cos A=
e, find the value of tan A+cot A​

Answer 1

Answer:

cosA = e

then, sinA will be

sinA = √1-e^2. ( sin^2A + cos^2A = 1)

we have to find tanA + cotA

so, sinA /cosA + cosA/sinA

taking LCM we get

sin^2A + cos2A / cosA(sinA)

= 1/cosA( sinA) by ( sin^2A + cos^2A = 1)

putting values of cosA and sinA we will get -.

tanA + cotB = 1/e(√1-e^2)
