Step-by-step explanation:
Use the Product Rule for derivatives, which states that:
In the function we are given, , we can break it up into two factors: -x is being multiplied by cos3x.
Now, we have the factors:
Before using the product rule, let's find the derivative of cos3x using the chain rule and the power rule.
Now let's apply the product rule to f(x) = -xcos3x.
Simplify this equation.
Multiply x and 3 together and remove the parentheses.
Therefore, this is the derivative of the function .
Answer:
The proof is given below.
Step-by-step explanation:
Given a parallelogram ABCD. Diagonals AC and BD intersect at E. We have to prove that AE is congruent to CE and BE is congruent to DE i.e diagonals of parallelogram bisect each other.
In ΔACD and ΔBEC
AD=BC (∵Opposite sides of parallelogram are equal)
∠DAC=∠BCE (∵Alternate angles)
∠ADC=∠CBE (∵Alternate angles)
By ASA rule, ΔACD≅ΔBEC
By CPCT(Corresponding Parts of Congruent triangles)
AE=EC and DE=EB
Hence, AE is conruent to CE and BE is congruent to DE
