how can i remember the trigonometric ratios of specific and complementary angles
Consider the right angled triangle shown in the below figure:
Where,
On the basis of the above triangle, we can follow the given table:
To remember the trignometrical ratio of angle, you can see the following method to remember the trigonometric ratios:
sin | cos | tan | |||
P | B | P | |||
H | H | B | |||
cosec | sec | cot |
In this table, P stands for perpendicular, B stands for base and H stands for the hypotenuse of the triangle.
The convention can be remembered as :
