simplify sin^2(2pix)+cos^2(2pix)

simplify

sin^{2} (2 π x) + cos^{2} (2 π x)

1

Solution steps

sin^{2} (2 π x) + cos^{2} (2 π x)

Use the Pythagorean identity:

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

= 1

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

f (x) = 3 + cot (3) + cos (x) sec (3)

tan (arccos (\frac{x}{19}))

tan (arccos (\frac{x}{20}))

\frac{( - cos ( - 2 πn ) )}{πn}
