put in simplest form
the denominator of a fraction is 4 more than the numerator. if both numerator and denominator are increased by eight, the simplified results is 8/9. find the original fraction.
Find a parametric representation of the surface z=3x+4y.
Let z=(e^x)(cos(xy)). Find the z-intercept of the equation of the tangent plane to the surface at (1, pi/2, 0).
use the law of cosines to find the side of each triangle. round the answer to nearest tenth. angle(A ) = 58 degree side (b) = 9 side (c) =12 find side (a) ?
So this is a equation. 2x+24=2/7x
use an angle sum identity to calculate the exact value of tan(75).
