Verify

Solution Steps

Evaluate trigonometric functions in the problem

$$4 \sin(0) 0.9993908270190958 = 2 \cdot 0.03489949670250097$$

Multiply 0.9993908270190958 and 4 to get 3.9975633080763832.

$$3.9975633080763832\sin(0)=2\times 0.03489949670250097$$

Get the value of \sin(0) from trigonometric values table.

$$3.9975633080763832\times 0=2\times 0.03489949670250097$$

Multiply 3.9975633080763832 and 0 to get 0.

$$0=2\times 0.03489949670250097$$

Multiply 2 and 0.03489949670250097 to get 0.06979899340500194.

$$0=0.06979899340500194$$

Compare 0 and 0.06979899340500194.

$$\text{false}$$
