prove 1+tan^2(3/4)=sec^2(x)

prove

1 + tan^{2} (\frac{3}{4}) = sec^{2} (x)

False

Solution steps

1 + tan^{2} (\frac{3}{4}) = sec^{2} (x)

Show that the two sides are not equal

\Rightarrow False

2 sin (2 x) + cot (2 x) = csc (2 x) - cos (2 x)

sin (\frac{3 π}{4}) = \frac{1}{2}

sin (c) = 2 sin (\frac{c}{2}) cos (\frac{c}{2})

\frac{5 sin ( 2 θ )}{2 sin ( θ )} = 5 cos (θ)

(1 - cos (x))^{2} = 1 + cos^{2} (x)
