`(dy)/(dx)=y tan x , y = 2` यदि x = 0 |
|
Answer» दिया है, `(dy)/(dx)=y tan x` `implies (1)/(y)dy=tan xdx` `implies int (1)/(y) dy = int tan x dx` `implies log|y|==log|(secx)|+log|C|` `implies logy=log|(C sec x)|` `impliesy=Csecx` अब, y = 1 तथा x = 0 रखने पर, 1 = C sec 0 implies `1 = C xx 1 implies C = 1` C = 1 रखने पर, y = sec x जोकि अभीष्ट विशिष्ट हल है। |
