prove 2tan^2(x)+sec^2(x)-2=0

prove

2 tan^{2} (x) + sec^{2} (x) - 2 = 0

False

Solution steps

2 tan^{2} (x) + sec^{2} (x) - 2 = 0

Show that the two sides are not equal

\Rightarrow False

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

tan (\frac{π}{3}) sin (\frac{2 π}{3}) = 1 + sin (\frac{π}{6})

2 cot (x) + cos (x) - sec (x) = cot (x)

(tan (θ) + cot (θ)) sin (θ) cos (θ) = 1

3 (tan (x)) + 12 = 3
