The differential equation dy/dx= 35/ (y 1/8 25x 2 y 1/8 has an implicit general solution of the form F (x,y)=K In fact, because the differential equation is separable, we can define the solution curve implicitly by the form F (x)=G (x)H (y)=K Find such solution and then give the related functions requestedPartial derivatives of composite functions of the forms z = F (g(x,y)) can be found directly with the Chain Rule for one variable, as is illustrated in the following three examples Example 1 Find the xand yderivatives of z = (x 2 y 3 sinx) 10Suppose that x, yand zare functions of one variable t Then w= f(x;y;z) becomes a function of t Divide the equation above to get the derivative of f, df dt = f x dx dt f y dy dt f z dz dt This is an instance of the chain rule Example 111 Let f(x;y;z) = xyzz2 Suppose that x= t2, y= 3=t and z= sint Then f x= yz f y= xz and f z = 2z

In order to change the fraction from a complex fraction to a simple fraction, we will multiply the numerator, 3, by the reciprocal of the denominator f (g (x))=3/ (22x)/x which would become f (g (x))= (3) x/ (22x) => f (g (x))=3x/ (22x) This is the simplified form of the fraction We already know that x cannot be equal to 2 or 0, asY u v y v s x u v y s u r s { s u Q E F G X I F U X Q O j N C X Q P X !& ' (# ) # ) " * ( % ' !

In this video I try to explain what a function in maths is I once asked myself, why keep writing y=f(x) and not just y!??The derivative of a function y = f(x) of a variable x is a measure of the rate at which the value y of the function changes with respect to the change of the variable x It is called the derivative of f with respect to x If x and y are real numbers, and if the graph of f is plotted against x, derivative is the slope of this graph at each pointX2Xand V ˆY is a neighborhood of f(x), then V ˙W where W is an open neighborhood of f(x) Then f 1(W) is an open neighborhood of xand f 1(W) ˆf 1(V), so f (V) is a neighborhood of x, which shows that fis continuous Conversely, suppose that f X!Y is continuous and V ˆY is open If x2f 1(V), then V is an open neighborhood of f(x), so the
