area y=sin(2x),y=cos(2x),x=0,x= pi/4

area

y = sin (2 x), y = cos (2 x), x = 0, x = \frac{π}{4}

2 - 1

Decimal

0.41421 \dots

Solution steps

Apply the area formula:

\int_{0}^{\frac{π}{4}} ∣ sin (2 x) - cos (2 x) ∣ d x

Solve

\int_{0}^{\frac{π}{4}} ∣ sin (2 x) - cos (2 x) ∣ d x : 2 - 1

The area is:

= 2 - 1

l o n g d i v i s i o n \frac{4 x ^{2} - 3}{x - 1}

t an g e n t \frac{2}{3 x + 5}

\int \frac{cot ( x )}{ln ( sin ( x ) )} d x

x \to 3 - lim (\frac{x ^{3}}{x ^{2} - 9})

\int_{0}^{1} 2 x e^{- x^{2}} d x
