let f(x)=1.013x^5 −5.262x^3 −0.01732x^2 +0.8389x
−1.912. Evaluate f(2.279) by first calculating
(2.279)^2 ,(2.279)^3 ,(2.279)^4 and(2.279)^5 using
four−digit round arithmetic. hence,compute
the absolute and relative errors.
solve for p,q,s in terms of c.
• (((qs)/(q−sp)))^2 −s(((qs)/(q−sp)))+p=0
• (((q+c)/(p+1)))^2 =sp−q
• (q−cp)(p+1)^2 =(q+c)^3
I have to find non zero real x=−(((q+c)/(p+1))) .
For what value of k the roots of the equation
((x^2 −2x)/(4x−1))=((k−1)/(k+1))
will have same value but with opposite symbol(like x=a and −a)
i mean the two valuea of x will be this type
x=2 and −2(both 2 but opposite symbols)
