If normal to the curve `y = f(x)` at a point makes `135^@` angle with x-axis, then at that point `dy/dx` equals to.

If tangent to the curve y=f(x) at any point is parallel to y -axis,then at that point (dy)/(dx) equals to

The point on the curve y^(2)=x where tangent makes 45^(@) angle with x-axis, is

The point on the curve y^(2)=x where tangent makes 45^(@) angle with x-axis, is

If the normal to the curve y = f(x) at the point (3, 4) makes an angle 3pi//4 with the positive x-axis, then f'(3) is :

If the tangent line to the curve y = f(x) at a point is parallel to the X-axis, what is the value of dy/dx ?

If the normal to curve y = f (x) at the point (3,4) makes an angle (3pi)/(4) with positive x-axis then f'(3) equals:

If the normal to the curve y =f(x) at the point (1, 2) makes an angle 3pi//4 with the positive x-axis, then f'(1) is

If the normal to the curve y=f(x) at the point (3,4) makes an angle (3pi)/4 with the positive x-axis, then f'(3)= (a) -1 (b) -3/4 (c) 4/3 (d) 1
