simplify 2sin(A+pi/4)

simplify

2 sin (A + \frac{π}{4})

2 sin (A) + 2 cos (A)

Solution steps

2 sin (A + \frac{π}{4})

Rewrite using trig identities

= 2 \cdot \frac{2 sin ( A ) + 2 cos ( A )}{2}

Simplify

2 \cdot \frac{2 sin ( A ) + 2 cos ( A )}{2} : 2 sin (A) + 2 cos (A)

= 2 sin (A) + 2 cos (A)

sin (4 x + 2 π)

sin (13 5^{\circ} - θ)

(tan (4 x - \frac{3}{4} π))^{2}

cos (x) - cos (x + \frac{π}{2})

sin (2 π x) + sin (2 π x - π)

What is 2sin(A+pi/4) ?
The solution to 2sin(A+pi/4) is sqrt(2)sin(A)+sqrt(2)cos(A)
