cos(x)= 7/25

cos (x) = \frac{7}{25}

x = 1.28700 \dots + 2 πn, x = 2 π - 1.28700 \dots + 2 πn

Solution steps

cos (x) = \frac{7}{25}

Apply trig inverse properties

x = arccos (\frac{7}{25}) + 2 πn, x = 2 π - arccos (\frac{7}{25}) + 2 πn

Show solutions in decimal form

x = 1.28700 \dots + 2 πn, x = 2 π - 1.28700 \dots + 2 πn

2 sin (3 x) + 2 = 0

0 = cos (θ)

sec^{2} (x) + 3 tan (x) = 5

2 sin (θ) + 1 = csc (θ)

cot (x) - 1 = csc (x)
