solvefor x,cos(x)=-(sqrt(26))/(26)

solve for

x, cos (x) = - \frac{26}{26}

x = 1.76819 \dots + 2 πn, x = - 1.76819 \dots + 2 πn

Degrees

x = 101.30993 \dots^{\circ} + 36 0^{\circ} n, x = - 101.30993 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (x) = - \frac{26}{26}

Apply trig inverse properties

cos (x) = - \frac{26}{26}

General solutions for

cos (x) = - \frac{26}{26}

cos (x) = - a \Rightarrow x = arccos (- a) + 2 πn, x = - arccos (- a) + 2 πn

x = arccos (- \frac{26}{26}) + 2 πn, x = - arccos (- \frac{26}{26}) + 2 πn

x = arccos (- \frac{26}{26}) + 2 πn, x = - arccos (- \frac{26}{26}) + 2 πn

Show solutions in decimal form

x = 1.76819 \dots + 2 πn, x = - 1.76819 \dots + 2 πn

6 cot (x) + 5 = - 1

11 csc (x) + 15 = 9 csc (x) + 19

sin^{2} (x) = \frac{tan ( x )}{2}

98 \cdot sin (θ) - 19.6 \cdot cos (θ) = 75.1

\frac{( sin ( x ) + tan ( x ) )}{1 + cos ( x )} = m \cdot sec (x)
