Why is a “normal” tangent graph uphill, but a “normal” COtangent graph downhill? Use unit circle ratios to explain.
Tangent and cotangent are opposites of each other. Tangent=sin/cos. Whenever cos=0, tan is undefined because there would have to be asymptotes. The graph would go in a positive direction since they are positive in Quadrant 1 and Quadrant 3. Cotangent= cos/sin. Cotangent is positive in Quadrant 1 and Quadrant 3 as well. The asymptote begins at (0,0) where Quadrant 1 is.
