cos(x)= 1/(sqrt(37))

cos (x) = \frac{1}{37}

x = 1.40564 \dots + 2 πn, x = 2 π - 1.40564 \dots + 2 πn

Solution steps

cos (x) = \frac{1}{37}

Simplify

\frac{1}{37} : \frac{37}{37}

Apply trig inverse properties

x = arccos (\frac{37}{37}) + 2 πn, x = 2 π - arccos (\frac{37}{37}) + 2 πn

Show solutions in decimal form

x = 1.40564 \dots + 2 πn, x = 2 π - 1.40564 \dots + 2 πn

\frac{sin ( 2 x )}{cos ( x )} = 4 + sin (2 x) \cdot tan (x)

sin (x) = 0.2174

x, arccot (x^{2}) y = arccot (x^{2})

\frac{50}{33} = \frac{sin ( x )}{sin ( 12 0 ^{\circ} - x )}

cot (x) csc (x) = cos (x)
