• Mod 7, Inv 8, #10,11 10:a The period of the tangent function is Pi. b The vertical asymptotes occur at integer multiples of pi/2 this is because cos(n*pi/2)=0 when n is an integer. c The ratio of sin and cos always have the same sign when they are in opposite quadrants. In I both are positive, in III they are both negative so the ratio is positive. In 2 sign is positive and cos is negative, but in 4 those are switched, so the ratio is always negative. And tangent is the slope of the line, and ratio of sin to cos.
