Linear Equations
We'll begin the solving portion of this chapter by solving linear equations.
Standard form of a linear equation:
A linear equation is any equation which can be written in the form
ax + b =0
where a and b are called as real numbers and x is a variable. It form is called the standard form of a linear equation. Note that mostly linear equations will not begin in this form. Also, the variable may or may not be an x thus don't get too locked into seeing an x always there.
WRITE the condition that should be fulfilled by two matrices A&B to get the product AB and BA
Find the standard form of the equation of the parabola with a vertex at the origin and a focus at (0, -7).
By pigeonhole principle, show that if any five numbers from 1 to 8 are chosen, then two of them will add upto 9. Answer: Let make four groups of two numbers from 1 to 8 like
ABC is a right-angled isosceles triangle, right-angled at B. AP, the bisector of ∠BAC, intersects BC at P. Prove that AC 2 = AP 2 + 2(1+√2)BP 2 Ans: AC = √2AB (Sinc
Question 1: (a) Show that, for all sets A, B and C, (i) (A ∩ B) c = A c ∩B c . (ii) A ∪ (B ∩ C) = (A ∪ B) ∩ (A ∪ C). (iii) A - (B ∪ C) = (A - B) ∩ (A - C).
