Visit to main page or of the page. Answer : It is known that the equation of the line through the points, x 1, y 1, z 1 and x 2, y 2, z 2 , is Since the line passes through the points, 3, — 4, — 5 and 2, — 3, 1 , its equation is given by, Therefore, any point on the line is of the form 3 — k, k — 4, 6k — 5. Union and Intersection of sets. Derivative introduced as rate of change both as that of distance function and geometrically. Whenever we compare two quantities, they are more likely to be unequal than equal.

Sections of a cone: circle, ellipse, parabola, hyperbola, a point, a straight line and a pair of intersecting lines as a degenerated case of a conic section. The plane in equation 1 is perpendicular to Its direction ratios, a2, b2, c2, are 1, — 1, and 1. Q7 : Find the intercepts cut off by the plane Answer : Dividing both sides of equation 1 by 5, we obtain It is known that the equation of a plane in intercept form is , where a, b, c are the intercepts cut off by the plane at x, y, and z axes respectively. We suggest you do all the chapters from Concept Wise, so that your concepts are cleared. We have experienced faculty members who leave no stone unturned in helping the students to score the best. The locus of a point that moves in an identical distance from 2 points, is normal to the line joining both the points. Q15 : Find the shortest distance between the lines and Answer : The given lines are and It is known that the shortest distance between the two lines, , is given by, Comparing the given equations, we obtain Substituting all the values in equation 1 , we obtain Since distance is always non-negative, the distance between the given lines is units.
