Step 4: Simplify the expression for kThis simplifies to:k=−1±√1+4yx2 Step 5: Rewrite k in terms of dydxThus, we have:dydx=−1±√1+4yx2 Step 6: Separate variables for integrationWe can separate variables to integrate:dx=2−1±√1+4yxdy Step 7: Integrate both sidesIntegrati...
2. 2cos(x)−1=0 Step 4: Solve cos(2x)=0The general solution for cosθ=0 is:θ=π2+nπ,n∈ZSo,2x=π2+nπ⟹x=π4+nπ2 Step 5: Solve 2cos(x)−1=0Rearranging gives:cos(x)=12The general solution for cosx=12 is:x=π3+2kπorx=−π3+2kπ,k∈Z Final Solutions...
