Describe all solutions to the equation sinxcosx=0

1 answer:

7 0

You have 2 factors (sinx)(cosx) = 0 As usual just set the factors = 0 sinx = 0 and cosx = 0 you will get the same answers with a lot less hassle. In my opinion (: I don't know if this is enough but hope it helps

Ksivusya [100]

Answer:

there is no solution

Step-by-step explanation:

Expand.

15x+35+2x=7x+10x-4515x+35+2x=7x+10x−45

2 Simplify 15x+35+2x15x+35+2x to 17x+3517x+35.

17x+35=7x+10x-4517x+35=7x+10x−45

3 Simplify 7x+10x-457x+10x−45 to 17x-4517x−45.

17x+35=17x-4517x+35=17x−45

4 Cancel 17x17x on both sides.

35=-4535=−45

5 Since 35=-4535=−45 is false, there is no solution.

Graph each line using intercepts 1/4 x + 2y =2

Leno4ka [110]

The given equation is,

$\frac{1}{4}x+2y=2$

It can be rewritten in the form of y=mx+c, where c is the y intercept.

Hence,

$\begin{gathered} 2y=-\frac{1}{4}x+2 \\ y=\frac{-1}{4\times2}x+\frac{2}{2} \\ y=\frac{-1}{8}x+1 \end{gathered}$

Put different values for x and find value of y.

When x=0, y=1.

When x=1,

$y=\frac{-1}{8}+1=\frac{7}{8}$

The graph is,
