Sample Maths & GAT questions
1. The value of cos 0 degrees is:
- (A) 0
- (B) 1
- (C) 0.5
- (D) Undefined
Show answer
(B) 1. Concept: Trigonometric ratios at standard angles come from a right-angled triangle or the unit circle. Formula: cos θ = adjacent / hypotenuse; on the unit circle cos θ = x-coordinate of the point at angle θ. Steps: At θ = 0°, the point on the unit circle is (1, 0) cos 0° = x-coordinate = 1 (sin 0° = 0) Why others are wrong: - A) 0 is sin 0° (or cos 90°). - C) 0.5 is cos 60°. - D) Undefined applies to tan 90° or sec 90°, never to cos. Remember: Standard table (0°, 30°, 45°, 60°, 90°): sin = 0, ½, 1/√2, √3/2, 1; cos is the same list reversed. Trick: sin θ = √n/2 with n = 0,1,2,3,4.
