Is sin(cot(x)+tan(x))=sec(x) ?

The answer to whether sin(cot(x)+tan(x))=sec(x) is False

Popular >

prove sin(cot(x)+tan(x))=sec(x)

prove

sin (cot (x) + tan (x)) = sec (x)

False

Solution steps

sin (cot (x) + tan (x)) = sec (x)

Show that the two sides are not equal

For

sin (cot (x) + tan (x)) = sec (x)

plug in

x = 1

sin (cot (1) + tan (1)) = 0.80879 \dots

sin (cot (1) + tan (1))

Refine to a decimal form

= 0.80879 \dots

sec (1) = 1.85081 \dots

sec (1)

Refine to a decimal form

= 1.85081 \dots

The two sides are not equal

\Rightarrow False

sin^{2} (2 x) = 4 sin^{2} (x) \cdot cos^{2} (x)

\frac{1 + tan ^{2} ( B )}{csc ^{2} ( B )} = tan^{2} (B)

\frac{1}{cos ( x ) + 1} + \frac{1}{cos ( x ) - 1} = - 2 csc (x) (cot (x))

\frac{sec ( x ) csc ( x )}{2} = csc (2 x)

- sec^{2} (x) = - tan^{2} (x) - 1
