cos(x)= 60/61 ,cos(2x)

cos (x) = \frac{60}{61}, cos (2 x)

No Solution for x \in R

Solution steps

cos (x) = \frac{60}{61}, cos (2 x)

Apply trig inverse properties

cos (x) = \frac{60}{61}

General solutions for

cos (x) = \frac{60}{61}

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

x = arccos (\frac{60}{61}) + 2 πn, x = 2 π - arccos (\frac{60}{61}) + 2 πn

x = arccos (\frac{60}{61}) + 2 πn, x = 2 π - arccos (\frac{60}{61}) + 2 πn

Solutions for the range

cos (2 x)

No Solution for x \in R

x, tan (3 x) = - \frac{1}{3}

arcsin (\frac{x}{3 ^{2} + x ^{2}}) = 0.01117

cot (x) - 3 = csc (x)

cos (b) = 0.47

- 6 = - 5 + cos (θ)
