see explanation...

Explanation:

First, multiply out in the numerator:

#(sin(t) + cos(t))^2/(sin(t)cos(t)) = (sin^2(t) + 2sin(t)cos(t) + cos^2(t))/(sin(t)cos(t) )#

Re-order the terms in the numerator a bit, and use the fact that #sin^2(t) + cos^2(t) = 1#, giving:

#(1 + 2sin(t)cos(t))/(sin(t)cos(t))#
#=1/((sin(t)cos(t)) )+ (2(sin(t)cos(t)))/(sin(t)cos(t))#

...you can now factor/separate the first term. Also, note that in the right term, the #sin(t)cos(t)# in numerator and denominator cancels out. So you have:

#(1/sin(t)) * (1/cos(t)) + 2#

...now remember #1/cos(t) = sec(t)#, and #1/sin(t) = csc(t)#, so it all works out to:

#csc(t)sec(t) + 2#

GOOD LUCK
