Trig Identity (secx + 1)/(secx 1) + (cosx + 1)/(cosx 1) = 0 YouTube
Secx = 1/Cosx. 1 sec(x) 1 sec ( x) apply the reciprocal identity to sec(x) sec. Web you are right.
Sec(x) sec ( x) apply the reciprocal identity to sec(x) sec ( x). Web cscx = 1 / sinx sinx = 1 / cscx secx = 1 / cosx cosx = 1 / secx tanx = 1 / cotx cotx = 1 / tanx tanx = sinx / cosx cotx = cosx / sinx pythagorean identities sin 2 x + cos 2. Web trigonometry verify the identity sec (x)=1/ (cos (x)) sec(x) = 1 cos(x) sec ( x) = 1 cos ( x) start on the left side. Web trigonometry verify the identity cos (x)=1/ (sec (x)) cos (x) = 1 sec(x) cos ( x) = 1 sec ( x) start on the right side. Just by looking at the definition of $\sec(x)$, one can clearly see that $$\sec (x) = \frac{1}{\cos (x)}$$ but don't just take my word for it. 1 sec(x) 1 sec ( x) apply the reciprocal identity to sec(x) sec. Web you are right.
