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

prove

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

False

Solution steps

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

Show that the two sides are not equal

For

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

plug in

x = 1

cos (1) + sin (1) + tan (1) = 2.93918 \dots

cos (1) + sin (1) + tan (1)

Refine to a decimal form

= 2.93918 \dots

sec (1) = 1.85081 \dots

sec (1)

Refine to a decimal form

= 1.85081 \dots

The two sides are not equal

\Rightarrow False

81 - 9 (3 sin (x))^{2} = 4 sin (x) + 8

cot (x) \cdot cos (x) + sin (x) = csc (x)

(1 - cos^{2} (a)) \cdot (1 + tan^{2} (a)) = tan^{2} (a)

csc (x) \cdot tan (x) + sec (x) = 2 sec (x)

(cos (x) + sin (x))^{2} = 1 + 2 cos (x) sin (x)
