1) Could someone please help me out on these. How do I find the lowest positive root of Y=2-3*SIN(0.5*X) I can see it on the plotter but I cant do it on paper. 2) a) Solve TAN(3*V+300) = -0.2 in the interval 1800 < or = V < or = 2700 b) Using the equation calculate the exact value of TAN 150 Thankx for your time. A big hug in advance. Eva Hellqvist. Stockholm Sweden. Hellqvisteva@hotmail.com
