Question

Suppose, 2amn = x(m2 + n2)
(√a+x)/(a-x)=?

Answer 1

Answer:

Step-by-step explanation:

d(ax−by) f (ax − by) · d(ax−by) dx. = −1 b exp. (. −x b. ) f + a exp. (. −x b. ) f (ax − by) ... 2 − 2ut + 2x = 0, and hence, u = t +. √ t2 − 2x. 7. u (x, y) = exp. ( x x2−y2. ) ... m2n2 cos mx cos ny. (e) f (x, y) = ∞. ∑ m=1. 2(−1)m+1 m sin mx sin y. (g) f (x, y) = ∞ ... Hint: Suppose R is the rectangle 0 ≤ x ≤ a, 0 ≤ y ≤ b and ∂R is.
