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

prove

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

False

Solution steps

(sin (x) + cos (x)) \cdot 2 = 1 + sin (2 x)

Show that the two sides are not equal

\Rightarrow False

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

sec (2 α) 2 - sec (2 α) = sec (2 α)

\frac{sin ( 2 θ )}{sin ( 4 θ )} = \frac{1}{2} sec (2 θ)

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

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

Is (sin(x)+cos(x))2=1+sin(2x) ?
