prove 5tan(2t)+3=3

Solution

prove

5 tan (2 t) + 3 = 3

False

Solution steps

5 tan (2 t) + 3 = 3

Show that the two sides are not equal

For

5 tan (2 t) + 3 = 3

plug in

t = 1

5 tan (2 \cdot 1) + 3 = - 7.92519 \dots

5 tan (2 \cdot 1) + 3

Refine to a decimal form

= - 7.92519 \dots

The two sides are not equal

\Rightarrow False

p ro v e (1 + sin (y)) (1 + sin (- y)) = cos^{2} (y)

p ro v e cos (6 x) + cos (2 x) = 2 cos (4 x) cos (2 x)

p ro v e cos (x) + cot (x) + sin (x) = csc (x)

p ro v e cos (- θ) csc (- θ) tan (- θ) = 1

p ro v e sec (x) - 2 tan (x) = 0
