Suppose that the current flowing in an electric circuit is the sum (superposition) of two alternating currents, one given by I1 = 2 cos t and the other given by I2 = −2 sin t at time t. Carefully describe the resulting current in the circuit.

thanks for that. 2sinx+1=0 should have got x=-30.

Re: need HELP on this question Hi. thanks for the reply. i solved the equation and got x =0 and x=-30. firstly is this correct and does this answer the question b.

thanks so much for the reply it really helped.once i solved the equation i got x=0 and x= 30 .

does anybody know how to solve this problem ?Consider two trigonometric functions y = cos 2x and y = 1 + sinx.(a) Write down the equation in x that you would solve to find the x coordinate of point(s) of intersection of those graphs on [0, 2∏]. (b) Solve your equation, and write down the...
