    Solve 5sinx +12cosx=6.5: 0-180 Degrees

    Homework Statement solve 5sinx +12cosx =6.5 between 0 and 180 degrees Homework Equations The Attempt at a Solution i tried squaring both sides. (5sinx +12cosx)^2= (6.5)^2 25sinx +60sinxcosx +60sinxcosx + 144cosx^2 =42.25

    Calculating Current in a Circuit with R1 = 10 Ohms and R2 = 8 Ohms

    Homework Statement the question is find the current through R1 R1= 10 Ohms R2=8 ohms current source=9A E=18VHomework Equations The Attempt at a Solution I have tried removing the current source and i get a short circuit on R1 and hence i obtain a current of 2.25A
