Question

how do we find the magnitude of any angle in trigonometrical ratios of standard angles ??​

Answer 1

Answer:

cos 90° = √(4/4) = 1. cos 90° = √(0/4) = 0. Since, we know the sin and cos value of the standard angles from the trigonometrical ratios table; therefore we can easily find the values of the other trigonometrical ratios of the standard angles.

Answer 2

Answer:

cos 90° = √(4/4) = 1. cos 90° = √(0/4) = 0. Since, we know the sin and cos value of the standard angles from the trigonometrical ratios table; therefore we can easily find the values of the other trigonometrical ratios of the standard angles.
