3. Direction cosines are:
l = cos a, m = cos a, n = cos a
∴ a = b = g
Answer. Direction cosines of a line making angle, a with x-axis, β with y-axis and γ with z-axis are l, m, n.
Where, l = cosα, m = cosβ, n = cos γ
Given, the line makes equal angles with coordinate axes.
So, a = b = g                    …(i)
Direction cosines are:
l = cosa, m = cosa, n = cosa
Since,

Answer. The smaller area enclosed by the circle
x2 + y2 = 4 and the line, x + y = 2 is
represented by the shaded area ACBA as :

It is given that we have to find the area bounded by the curve y = x3, the x-axis and the ordinates x = – 2 and x = 1.
First of all, draw the curve y = x3 and
x = – 2 the ordinary x = 1. Then highlight the bounded portion between the curve and the ordinates. Which is shown in the figure.

Now, calculate the area of the bounded figure by breaking the curve in two parts: the first part is the curve between x = – 2 and
x = 0, and the second part is the curve between
x = 0 and x = 1.
We have studied that the area bounded by the curve and x-axis is given by

Given ordinates bound the curve on the left and right side which gives the upper and lower limits of the integration.
Now, the area of bounded figure is given by

Answer. Let P be the given point and Q be the foot of the perpendicular

Sample Paper Class 12 Mathematics Term 2 Set E

Let coordinates of Q be (2λ – 1, λ + 3, –2λ – 6)
Since Q lies in the plane 2x + y – 2z + 5 = 0 1
∴ 2(2λ – 1) + (λ + 3) – 2(–2λ – 6) + 5 = 0
⇒ 4λ – 2 + λ + 3 + 4λ+ 12 + 5 = 0
⇒ 9λ + 18 = 0
⇒ λ = – 2 1
∴ Coordinates of Q are (–5, 1, –2)
Length of the perpendicular from P to the plane
