How to use it?
- Equation:
-
Equation cos(pi*x)=0
- Equation (ctgx+3)^2+2a^3+3a^2=(a^2+2a+3)*(ctgx+3)
- Equation √3(cos4x+1)=2(2-cos4x)cos2x
-
Equation tg(x)=3
- Express {x} in terms of y where:
- (x^2+y^2-1)^3+x^2*y^3=0
- -1*x-19*y=-10
- 5*x+5*y=20
- 4*x-16*y=6
-
Identical expressions
- √ three (cos4x+ one)= two (two -cos4x)cos2x
- √3( co sinus of e of 4x plus 1) equally 2(2 minus co sinus of e of 4x) co sinus of e of 2x
- √ three ( co sinus of e of 4x plus one) equally two (two minus co sinus of e of 4x) co sinus of e of 2x
- √3cos4x+1=22-cos4xcos2x

0.333333333333333 (cos(4*x) + 1) = 2*(2 - cos(4*x))*cos(2*x)
$$\left(\cos{\left(4 x \right)} + 1\right)^{0.333333333333333} = 2 \left(2 - \cos{\left(4 x \right)}\right) \cos{\left(2 x \right)}$$
