Let p and q be polynomials with positive coefficients. consider the limit below. lim x→[infinity] p(x) q(x) (a) find the limit if the degree of p is less than the degree of q. 0 (b) find the limit if the degree of p is greater than the degree of q.

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
