Question

sinC and cosC formula​

Answer 1

$\boxed{sinC}$

$sinc(x) = \frac{ \sin(x) }{x}$

$\boxed{cosC}$

$cos(θ) = Adjacent / Hypotenuse$

Answer 2

CONSIDER THE ATTACHED TRIANGLE .

FORMULAE :-

$sin \: c \: = \: \frac{perpendicular}{hypotenes} = \frac{ab}{ac} \\ \\ cos \: c \: = \frac{base}{hypotenues} = \frac{bc}{ac}$
