1. ### solve the equation tan t + sec t = 1?

tan( t ) + sec( t ) = 1 sin( t )/cos( t ) + 1/cos( t ) = 1 [sin( t ) + 1]/cos( t ) = 1 sin( t ) + 1 = cos( t ) # ...( t ) + 2 sin( t ) + 1 = 1 - sin²( t ) 2 sin²( t ) + 2 sin( t ) = 0 2 sin( t ) [sin( t ) + 1] = 0 sin( t ) = 0, t = 0 + π...

8. ### Solve this Equation for t .?

yep, messy, and didn' t have a chance to answer before: 3sqrt(2t - 3) = 11 - 2sqrt(7 - t ) square both sides: 9(2t - 3) = 121 - 44sqrt(7 - t ) + 4(7 - t ) 18t - 27 = 121 - 44sqrt(7 - t ) + 28 - 4t 22t - 176 = -44sqrt(7 - t ) divide everthing by 22: t - 8 = -2sqrt(7 - t ) square...
