cos(x)sin(x)=1

cos (x) sin (x) = 1

No Solution for x \in R

Solution steps

cos (x) sin (x) = 1

Rewrite using trig identities

cos (x) sin (x)

Use the Double Angle identity:

2 sin (x) cos (x) = sin (2 x)

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

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

\frac{sin ( 2 x )}{2} = 1

Multiply both sides by

2

\frac{sin ( 2 x )}{2} = 1

Multiply both sides by

2

\frac{2 sin ( 2 x )}{2} = 1 \cdot 2

Simplify

sin (2 x) = 2

sin (2 x) = 2

- 1 \leq sin (x) \leq 1

No Solution for x \in R

24 arctan (x) = 4 π

cos^{2} (x) - sin (x) - 1 = 0

5 cos (x) + 12 sin (x) = 6

- 73 tan (θ) + 5 = 26

6 sin (x) = cos (x) - 3
