Answered by abubakkar80474

Answer:

sin 60° = √3/4 = √3/2; 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
