  1. #csc17xsec17x#

Explanation:

#cot17x+tan17x#

#(cos17x)/(sin17x)+(sin17x)/(cos17x)#

#((cos17x)(cos17x)+sin(17x)(sin17x))/(sin17xcos17x)#

#(cos^2 17x+sin^2 17x)/(sin17xcos17x)#

#1/(sin17xcos17x#

Phytagorean Identity: #sin^2(alpha)+cos^2(alpha)=1#

#(1/(sin17x))(1/(cos17x))#

#->csc17xsec17x#
