Equation x^2-8=0
Equation x^2=-3
Equation x^4-2*x^3+x^2-1=0
Express {x} in terms of y where:
-9*x-12*y=-19
6*x+7*y=-10
4*x-11*y=-2
-5*x-2*y=-14
Derivative of:
f*(x)
Identical expressions
f*(x)= six *cos(x)-(six / five)*x
f multiply by (x) equally 6 multiply by co sinus of e of (x) minus (6 divide by 5) multiply by x
f multiply by (x) equally six multiply by co sinus of e of (x) minus (six divide by five) multiply by x
f(x)=6cos(x)-(6/5)x
fx=6cosx-6/5x
f*(x)=6*cos(x)-(6 divide by 5)*x
Similar expressions
f*(x)=6*cos(x)+(6/5)*x

                 6*x
f*x = 6*cos(x) - ---
                  5

$$f x = - \frac{6 x}{5} + 6 \cos{\left(x \right)}$$
