Question

tan A is not defined at (B 30 (A) 45(

90 (D) 0​

Answer 1

The correct option for  tangent function is (D) 0 and 90.

The tangent function is defined as the ratio of the sine to the cosine of an angle. The tangent function is not defined at certain angles where the cosine of the angle is equal to zero.

The value of tan A is not defined at 90 (D) 0 degrees, because at these angles the cosine of the angle is equal to zero, making the ratio undefined.

At 90 degrees, Cos(90)=0 and Sin(90)=1, the ratio of Sin(90)/Cos(90) is not defined

At 0 degrees, Cos(0)=1 and Sin(0)=0, the ratio of Sin(0)/Cos(0) is not defined

Hence, the correct option is (D) 0 and 90.
