Let r cos θ = –1 and r sin θ = 1

On squaring and adding, we obtain r² (cos² θ + sin² θ) = 1+ 1

⇒ r² (cos² θ + sin²θ) = 2

⇒ r² = 2 [cos²θ + sin² θ = 1]

This is the required polar form.

ANSWER

Square root of 1-i

5t²-10t-15
=5(t²- 2t-3 )
=5 (t² - 3t + t - 3)
=5 [t(t-3) +1(t-3)]
= 5 (t+1) (t-3) ?

Prove the following identites

sec⁴x - sec²x = tan⁴x + tan²x

SOLUTION

LHS = sec⁴x - sec²x

= sec²x(sec²x - 1)

= (tan²x + 1)(tan²x) (∵ sec²x - tan²x = 1)

= tan⁴x + tan²x

=RHS

Hence proved.

The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values). Range: all y-values that are used (dependent values).
