Hello aspirant, some of the best books to learn trigonometry are-

• Trigonometry (9th Edition) by Lial, Margaret; Hornsby, John; Schneider, David I.
• Trigonometry - 4th edition by Mark Dugopolski
• Trigonometry Advanced Placement Version Sixth Edition:Trigonometry 2001st Edition: Trigonometry: I.M. Gelfand, Mark Saul

Thank you.

Dear Aspirant,

I have check the question it is misprint but I have tried to prove the Result hope this will help you.

here is the your answer:

recall your half-angle formula:

tan(x/2) = sinx/(1+cosx)

Now, we have

1+sec2A = (1+cos2A)/cos2A
= 1/[cos2A/(1+cos2A)]
= 1/[sin2A/(1+cos2A) * cos2A/sin2A]
= 1/(tanA cot2A)

hello,

This question will get solved by applying rules and derivation. and you have to understand why it has happened like this. For that go to your maths teacher and ask him/her to help you out and explain you the steps he uses to solve it.

Some questions are important

Specifically, they are the inverses of the sine , cosine, tangent , cotangent, secant, and cosecant functions , and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry.

Integrating the derivative and fixing the
