Abstract: We consider the pointwise weighted approximation by Bernstein operators. The related weight functions are Jacobi weights $w(x)\eg x^a{(1-x)}^b$ ( $0 . We obtain approximation equivalence theorems, using a weighted modulus of smoothness \omega^{2}_{\varphi^{\lambda}} {(f,t)}_{w}, which is an extension of~[5]. [ABSTRACT FROM AUTHOR]$
