Question

How to remember the trigonometric ratios of some specific angles easily,?

Answer 1

Heya....!!!!

HERE IS YOUR ANSWER

--------------------------------------------------

You don't need to learn the angles of all trigonometric function. Just learn the angles of sin. Else all you could find out by the terms of sin only. As the angles for cos goes reverse from 90°-0° in respect to sine.We already know that cosec= 1/sin , so you can find the angles of cosec by doing reciprocal of sine. Sec could be obtained by reciprocal of cos. Tan could be obtained by sin/cos.And cot could be obtain by reciprocal of tan. Thus just learn value of sine only.

Answer 2

hey...jenillia.... don't .... learn about any angle . ..you can find it........
just do that.....
after that.. you can find all ratios....
is it helpful...
