A quadrant is the area that is divided into the x and y axes
The quadrants in which tan and cot
are positive are I and III
The tangent of an angle is calculated as:
While the cotangent of the angle is calculated as:
The above equations mean that:
For the tangent and cotangent of an angle to be positive, then the sine and the cosine of the angle must have the same sign.
- In the first quadrant, the sine and the cosine angles are positive.
- In the third quadrant, the sine and the cosine angles are negative.
Hence, the quadrants in which tan and cot
are positive are I and III

8 goes in to 16 2 times so put 2 on the top. 8 x 2 is 16 so do 16 - 16 which is 0. 8 cant go into 0 so put a 0 on top. Bring down the 1; 8 cant go into 1 so bring down the 3. 8 can go into 13 1 time so put a 1 on top. 13 - 8 is 5 so the remainder is 5
