ANSWER

Find the equation of the plane which contains the line of intersection of the planes and whose x-intercept is twice its z-intercept. Hence find the equation of the plane passing through the point(2,3,-1) and parallel to the plane obtained above. Also find the equation and length of the perpendicular.

Aditi Mishra 5 years ago

An implicit function is a function that is defined implicitly by an implicit equation, by associating one of the variables (the value) with the others (the arguments). Thus, an implicit function for y in the context of the unit circle is defined implicitly by x2 + f(x)2 − 1 = 0.

Put y=x^2 and solve it by using integration by partial fraction

Sahil Kumar 5 years ago

The Right answer of this question should be:- I = (-1/√2)tan^(-1)(x/√2)+(2/√3)tan^(-1)(x/√3)+C

Sahil Kumar 5 years ago

Substitute x²=t and its derivative will be 2x=dt/dx then, put dx= dt/2x and x=√t and dx=dt/2√t. Now Solve the Required equation by the help of partial fraction. And finally integrate it!!
