prove cos(2x-40)=0.8

Solution

prove

cos (2 x - 40) = 0.8

Solution

False

Solution steps

cos (2 x - 40) = 0.8

Show that the two sides are not equal

\Rightarrow False

Popular Examples

prove cos(pi/2+x)=cos(x)prove

cos (\frac{π}{2} + x) = cos (x)

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

cos (x) - sin (2 x) = 1

prove (csc(6x)+cot(6x))/(csc(6x)-cot(6x))=tan(6x)prove

\frac{csc ( 6 x ) + cot ( 6 x )}{csc ( 6 x ) - cot ( 6 x )} = tan (6 x)

prove csc^4(x)-cot^4(x)=1+2cot^2(x)prove

csc^{4} (x) - cot^{4} (x) = 1 + 2 cot^{2} (x)

prove 1/(sin(x))sec(x)=tan(x)+cot(x)prove

\frac{1}{sin ( x )} sec (x) = tan (x) + cot (x)
