What is Coordinate Geometry in CBSE Class 11 Applied Maths?

Coordinate Geometry, often called analytic geometry or Cartesian geometry, is a branch of mathematics that employs algebraic equations to represent and analyze geometric figures on a coordinate plane.

In this, geometric figures such as points, lines, and curves are represented using coordinates and algebraic equations.

The coordinate system is typically the Cartesian coordinate system, which utilizes two perpendicular lines called axes (the x-axis representing the horizontal direction and the y-axis representing the vertical direction) to define a point uniquely in a plane using a pair of numerical coordinates.

To better understand the concept of coordinate geometry, consider the simple example of a point in a plane.

In the Cartesian coordinate system, a point is an ordered pair of numbers represented P (x,y), where x is the distance of the point from the y-axis (called the x-coordinate or abscissa), and y is the distance from the x-axis (called the y-coordinate or ordinate).

For instance, the point P (3,2) represents a point 3 units to the right of the y-axis and 2 units above the x-axis. This systematic approach allows for a seamless blend of algebra and geometry, facilitating the study of figures and spaces' shapes, sizes, and properties using algebraic methods.

CBSE Class 11 Applied Maths Coordinate Geometry Solved Sample Questions

To help you understand the type of questions asked in the exam, we have provided some sample questions for your reference here.

CBSE Applied Maths Coordinate Geometry on Circles

Q1) How are the points (0, 1), (3, 1) and (1, 3) situated with respect to the circle x 2 + y 2 – 2x – 4y + 3 = 0?

Answer: To check the position of a point to a circle, substitute the point in the circle equation.

For (0,1): 02+12−0−4(1)+3=002+12−0−4(1)+3=0 So, the point lies on the circle.

For (3,1) and (1,3), substituting them in the equation, we get values greater than 0. So, they lie outside the circle.

Q2) Obtain the equation of the circle orthogonal to both the circles x 2 + y 2 + 3x – 5y + 6 = 0 and 4x 2 + 4y 2 – 28x + 29 = 0 and whose centre lies on the line 3x + 4y + 1 = 0.

Answer: The given problem requires detailed calculation using the properties of orthogonal circles and the conditions they satisfy.

Q3) The chords of contact of the pair of tangents drawn from each point on the line 2x + y = 4 to the circle x 2 + y 2 = 1 pass through a fixed point.

Answer: Using the T = 0 condition, the chord of contact for the tangents from any point (h, k) to the given circle is ℎ+xy=1hx+ky=1

Class 11 Applied Maths Coordinate Geometry Questions on Straight Lines

Q1) Find the equation of the straight line, which makes an angle of 15° with the positive direction of the x-axis and cuts an intercept of length 4 on the negative direction of the y-axis.


Given that the line makes an angle of 15° with the positive direction of the x-axis, we have tan⁡(θ)=tan⁡(15°)tan(θ)=tan(15°). The slope m of the line is the value of tan(θ).

Now, m=tan(15°)

Using the value of tan⁡(15°)=2−3tan(15°)=2−√ 3​ (you can use trigonometric identities or a calculator), m=2−√ 3​

The line cuts an intercept of length 4 on the negative direction of the y-axis, so the y-intercept c=-4.

Using the slope-intercept form y=mx+c, y=(2−√ 4)x−4. That is the required equation of the line.
