How to use it?
- Equation:
-
Equation sin6x=1/2
- Equation tg(x)(ctg(x)-cos(x))=2sin(2x)^2
-
Equation tgx=-(3/4)
-
Equation 325+=276+183
- Express {x} in terms of y where:
- 15*x-15*y=16
- 9*x+18*y=6
- (x^2+y^2-1)^3+x^2*y^3=0
- -1*x-19*y=-10
-
Identical expressions
- tg(x)(ctg(x)-cos(x))= two sin(2x)^2
- tg(x)(ctg(x) minus co sinus of e of (x)) equally 2 sinus of (2x) squared
- tg(x)(ctg(x) minus co sinus of e of (x)) equally two sinus of (2x) squared
- tg(x)(ctg(x)-cos(x))=2sin(2x)2
- tgxctgx-cosx=2sin2x2
- tg(x)(ctg(x)-cos(x))=2sin(2x)²
- tg(x)(ctg(x)-cos(x))=2sin(2x) to the power of 2
- tgxctgx-cosx=2sin2x^2
-
Similar expressions
- tg(x)(ctg(x)+cos(x))=2sin(2x)^2
- tg(x)(ctg(x)-cosx)=2sin(2x)^2
tg(x)(ctg(x)-cos(x))=2sin(2x)^2 equation
The teacher will be very surprised to see your correct solution 😉
The solution
You have entered
[src]
2 tan(x)*(cot(x) - cos(x)) = 2*sin (2*x)
$$\left(- \cos{\left(x \right)} + \cot{\left(x \right)}\right) \tan{\left(x \right)} = 2 \sin^{2}{\left(2 x \right)}$$
