Question

one upon cos c equal to sec c​

Answer 1

Answer:

$\frac{1}{ \cos(c) } = \sec(c ) \\ sec(c) = sec(c) \: \: \: \: ( \frac{1}{cos} = sec)$

Hence,

LHS = RHS

Answer 2

$\huge\underline\frak\purple{Solution}$

$\large\implies\sf \large\frac{1}{cos(c)}\;=\large\sec(c)$

$\large\implies\sf \large\sec(c)\;=\large\sec(c)$

$\large\underline\bold\red{Note :-}$

$\large\implies\sf \huge\frac{1}{cos\theta}\;=\;sec\theta$
