A) \[\sin \theta \]
B) \[\cos \theta \]
C) \[\tan \theta \]
D) \[\cot \theta \]
Correct Answer: D
Solution :
At an instant approach the student will choose tanq will be the right answer. But it is to be seen here the curve makes the angle q with the V-axis. So it makes an angle (90 ? q) with the i-axis. So resistance = slope = tan (90 ? q) = cotq.
