tan^(2)xsecx+secx
= secx( tan^2 x + 1) , common factor
= secx(sec^2 x), by identity
= sec^3 x
(csct-sint)/(csct)
= (1/sint - sint)/(1/sint)
multiply top and bottom by sint
= (1 - sin^2 t)/1
= cos^2 t
[Note: i did these wrong apparently.. :( ]
Simplify the trigonometry expressions as much as possible.
(a). tan^(2)xsecx+secx
(b).(csct-sint)/(csct)
