Step-by-step explanation:
The secant function is the reciprocal function of the cosine function. Therefore, given that 
then, if 
then .
On the other hand, if cos (t) = 1/2 ⇒ t = ±
Then, the sin() =
Answer:
(a) x + y = 63 OR 3x = 63
(b) 21
(c) 42
Step-by-step explanation:
Let Vijay's age be x and Ajay's be y.
Ajay is <u>twice</u> as old as Vijay
==> Ajay's age = 2 × Vijay's age
==> <u>y = 2x</u>
<h3>(a)</h3>
<u>Sum</u> of their ages = 63
==> x + y = 63
<em>Substituting</em><em> </em><em>2</em><em>x</em><em> </em><em>for</em><em> </em><em>y</em><em>:</em>
==> x + 2x = 63
==> 3x = 63
<h3>(b)</h3>
<em>Solving the above-obtained equation:</em>
<u>==> x = 21</u>
<h3>(c)</h3>
Ajay's age = 2 times that of Vijay
==> y = 2x
==> y = 2×21
<u>==> y = 42</u>
