Solved example of trigonometric equations
The reciprocal sine function is cosecant: $\frac{1}{\csc(x)}=\sin(x)$
Move everything to the left hand side of the equation
Combining like terms $8\sin\left(x\right)$ and $-4\sin\left(x\right)$
Factor the polynomial $4\sin\left(x\right)-2$ by it's greatest common factor (GCF): $2$
Divide both sides of the equation by $2$
Zero divided by anything is equal to zero
Divide both sides of the equation by $2$
We need to isolate the dependent variable , we can do that by simultaneously subtracting $-1$ from both sides of the equation
$x+0=x$, where $x$ is any expression
We need to isolate the dependent variable , we can do that by simultaneously subtracting $-1$ from both sides of the equation
Multiply $-1$ times $-1$
Divide both sides of the equation by $2$
Divide both sides of the equation by $2$
Zero divided by anything is equal to zero
Divide both sides of the equation by $2$
Divide $1$ by $2$
The angles where the function $\sin\left(x\right)$ is $\frac{1}{2}$ are
The angles expressed in radians in the same order are equal to
