1=lcos(x)

1 = l cos (x)

x = arccos (\frac{1}{l}) + 2 πn, x = - arccos (\frac{1}{l}) + 2 πn

Solution steps

1 = l cos (x)

Switch sides

l cos (x) = 1

Divide both sides by

l; l \neq = 0

cos (x) = \frac{1}{l}; l \neq = 0

Apply trig inverse properties

x = arccos (\frac{1}{l}) + 2 πn, x = - arccos (\frac{1}{l}) + 2 πn

tan (2 x) = cos (2 x), 0 \leq x \leq π

5 sin (2 x) = 5 cos (x), 0 \leq x \leq 2 π

x, f = cos (x) cos (h y)

tan (x) = - \frac{1}{10}

tan (4 x) \cdot cot (x + 60) = 1
