Read Solve The Equation 3 Sin 2x Cos 2x - Updated
Open solve the equation 3 sin 2x cos 2x. 10x in pi4 3pi4 5pi4 7pi4 Applying the identity cos2x-sin2x cos2x we have sin2x-cos2x -cos2x In general cosu 0 u npi2 for some n in ZZ Thus we have sin2x - cos2x 0 -cos2x 0 2x npi2 for n in ZZ x npi4 for n in ZZ Restricting our values to the interval 0 2pi gives our final result. 22y - 8y 20y sixteen sin2x-cos2x. With trigonometric problems similar to this one you should always check if any trigonometric identites like the double-angle formulae can be used as these can often help youUsing your IB formula booklet you will see that the double-angle formula for sine issin2x 2sinxcosx Therefore we can rewrite the given equation from2cosx sin2xto2cosx 2sinxcosxNext we notice that both sides of the equation. Check also: answer and solve the equation 3 sin 2x cos 2x To find the second solution subtract the reference angle from to find the solution in the second quadrant.
Firstly since cos 2xequiv 1-2sin2 x we have that 2sin2 xequiv 1-cos 2x so our equation can be rewritten as cos 4x 3cos 2x 1 - cos 2x 0. The sine function is positive in the first and second quadrants.
