x=a secα dx = a secα tanα dα......(i) And y=b tanα dy = b sec²α dα.......(ii) Dividing both equations dy/dx= a/b cosecα Again differentiate wrt to x d²y/dx²= a/b (-cotα cosecα)×dα/dx = a/b(-cotα cosecα)×1/a secα tanα =-cot³α/b

x^y=e^x-y Taking log both side ylogx = x-yloge (loge=1) ylogx = x-y Differentiate both side w.r.t x y/x + logx dy/dx = 1 - dy/dx dy/dx(logx+1)= 1-y/x dy/dx = x-y/x(logx+1) = ylogx/x(logx+1) = logx/(logx+1)^2 ANSWER

Given : x^y=e^x-y taking log both side we get, ylogx =(x-y)loge=(x-y). .....1 when x=1 then y(log1)=(1-y)=y=1 Differentiate both side w.r.t 'x' y(1/x)+logx dy/dx = 1-dy/dx =dy/dx ( logx +1) = 1 - y/x = dy/dx = x-y/x(logx +1) when x=1 then, dy/dx= 1-1/1(log1+1) = 0

<style> body { font-family: 'Times New Roman', serif; } </style> </head> <body>Continuity:
A function is Continuous at a point if the value of function coincides with the limiting value at that point, else its differentiable
Mathematically,
f is continous if, $$\displaystyle \lim \limits_{x \to c} f(x) = f(c)
Take any example yourself for better understanding
