If 4 cos theta - 3 sec theta = tantheta, " then " theta=

Answer»

`THETA = n PI + (-1)^(n) BETA , n in Z " where SIN " beta = (1 + sqrt(17))/(8)`
`theta = n pi + (-1)^(n) beta , n in Z " where sin " beta = (-1 - sqrt(17))/(8)`
`theta = n pi + (-1)^(n) beta , n in Z " where sin " beta = (-1 + sqrt(17))/(4)`
`theta = n pi + (-1)^(n) beta , n in Z " where sin " beta = (-1sqrt(17))/(4)`
