BQ#4 - Unit T Concept 3

Tangent goes uphill because its positive in quadrants one and three and negative in quadrants two and four. Its positive in zero uphill and pi uphill etc. The asymptotes are in zero, pi/2, pi, 3pi/2 and 2pi because x is zero. The tangent graph starts at negative and goes uphill to be positive and to go to the next quadrant.
Cotangent goes downhill because its postive in quadrants one and three and negative in quadrants two and four, just like tangent. Its negative downhill pi/2 and 3pi/2 etc. The asymptotes are in zero, pi, and 2pi because y is zero. The cotangent graph starts positive and goes downhill to be negative its like the reciprocal of tangent.
