Answer :
Answer:
B. d = sin2e
Step-by-step explanation:
Use the following identity: 2cos(x)sin(x)=sin(2x)
Therefore
d = 2sine cose
can be written as
d=sin(2e)
However, if you want step by step (for example if your teacher does not give you formula sheets with identities let me know.
The horizontal distance of the hop can also be written as d = sin 2e, the correct option is B.
What is a Trigonometric Identity?
A trigonometric identity is used to solve a trigonometric Equation, it is based on the six trigonometric Ratios.
The horizontal distance of a hop by a frog is given by
d = 2 sine cose
By the trigonometric Identity sin 2x = 2 sinx cosx
From the above Identity, the horizontal distance of the hop can also be written as
d = sin 2e
Therefore, the correct option is B.
