The cosine function is negative in quadrant II

cos = x/r....in this quadrant, x is negative [r is always positive ]

The sine function is positive in quadrant I

sin = y/r.......x, y and r are all positive in the first quadrant

The cotangent function is negative in quadrant II

cot = x/y......x is negative and y is positive in quadrant 2
