prove sec(x)cos(x)=1

Solution

prove

sec (x) cos (x) = 1

Solution

True

Solution steps

sec (x) cos (x) = 1

Manipulating left side

sec (x) cos (x)

sec (x) cos (x) = 1

We showed that the two sides could take the same form

\Rightarrow True

Popular Examples

prove sec(x)-cos(x)=(tan^2(x))/(sec(x))prove

sec (x) - cos (x) = \frac{tan ^{2} ( x )}{sec ( x )}

prove (csc^2(x)-1)sec^2(x)=csc^2(x)prove

(csc^{2} (x) - 1) sec^{2} (x) = csc^{2} (x)

prove tan(x/2)=(1-cos(x))/(sin(x))prove

tan (\frac{x}{2}) = \frac{1 - cos ( x )}{sin ( x )}

prove cos(pi/4-x)+cos(pi/4+x)=sqrt(2)cos(x)prove

cos (\frac{π}{4} - x) + cos (\frac{π}{4} + x) = 2 cos (x)

prove sin^4(x)-cos^4(x)=-cos(2x)prove

sin^{4} (x) - cos^{4} (x) = - cos (2 x)
