There is Always a time in Exam for your Questions.

1) Yes there is Always a way to solve trignometry questions by shorcut. Just substitute any angle in 2 sides if 2 angles satisfies both the equations then try for another angle  by repeating this u will know the answers.

2) but it is very good if u dont use shortcuts. if u do that after crack JEE u can do nothing and u have to hace concept. so build your concepts

Dear Nitin ,

To learn simple Trigonometric formulas  the most commonly used technique is to revise the questions many times so as to revise the formulae. Learn The formulaes Early in the morning as they help to cross out your problems. Remember  trigonometry scores about 30% in iit jee.

Dear nithin,

Basic trigonometric ratios will be defined using the right angled triangle ABC given below , to later on move to trigonometry formulas.

Trigonometry Formulas

Trigonometric Ratios

Sin X = Opposite Side/ Hypotenuse

Cos X = Adjacent Side/ Hypotenuse

Sec X = 1/Cos X ; Csc X = 1/ Sin X; Tan X = Sin X/ Cos X; Cot X = Cos X/Sinx = 1/ Tan X

Trigonometric Formulas Sub topics

Pythagorean identities

Sin2X + Cos2 X = 1

Tan 2X + 1 = Sec2X

Cot2X + 1 = Csc2X


We are all IITians and here to help you in your IIT JEE preparation.

All the best.
