Plot the curves: 1. y = sin X + cos x. 2. y = 2x+ sinx. EXERCISES 3. y = e — sin 2 x. 4. y = a? + 2x — Z. 5. Show by the method of Art. 167 how to solve graphicallythe equation a^+(2a--3) = 0. Solve graphically the equations;6. 3ar-6a; + 2 = 0. 7. Sin 2 05 = 2 cos x. 167, 168] CURVE TRACING. HIGHER… … Fig. 122. (a) Trace r = a6. The angle 6 mnst, of course, be measured in radians, so thatr and $ may be plotted in units of length. (1) r increases indefinitely as 6 increases indefinitely.
