Jan 25, 2021 ... To find the solutions, we set each term to zero to get sin(2x) = 0 and sin(x) = 0. The sine function is zero at integral multiples of π. sin x is known as a periodic function that oscillates at regular intervals. Sine function crosses the x-axis at x = 0,π, and 2π in the domain. sinx = lim y→0+ sin(−y) = lim y→0+. (−siny)=0. Thus, sinx is continuous at 0. Furthermore, lim x→0 cosx = lim x→0 p. 1 − sin2 x = 1 = cos 0. So, cosx is ... Oct 18, 2006 ... a) What is the domain of f? Since you can't take the square root of a negative number, I set 1 - sinx > 0: . . . Mar 18, 2014 ... Solve the trig equation, involves using a double angle formula and factoring. Need more help?
