Let f(x)=8secx. Then f′′(π/9)

Mathematics

Ahat [919]3 years ago

f(x)=secx.

f'(x)=sec x tan x.

Use the product rule to find f ' '(x).

F ' '(x)=(secxtanx)tanx+secx(sec2x).

So, f ' '(x)=secxtan2x+sec3x.

Evaluate:f ' '(π4)=sec(π4)tan2(π4)+sec3(π4)=(√2)(1)2+(√2)3=√2+2√2=3√2.

How can you show two figures are congruent?
galina1969 [7]

If at least two sides and one angle of two triangles are similar, then the triangles are congruent.

What in mathematics is the congruent?

  • It is claimed that two figures are "congruent" if they can be positioned exactly over one another.
  • Both the shape and size of the bread slices are same if you lay one slice on top of the other.
  • Congruent refers to having precisely the same form and size.

Use the Third Angles Theorem for  two figures are congruent.

When two of a triangle's angles match up with two of another triangle's angles, the third angle must likewise match up.

If at least two sides and one angle of two triangles are similar, then the triangles are congruent.

What is the domain of this function
Sphinxa [80]

The domain is the set from which the function "starts", i.e. it is the set of the inputs you feed the function with.

In this case, the function starts from the set \{-2, 2, 3, 4\} and lands on the set \{3, 9, 12\}

So, the domain is the set \{-2, 2, 3, 4\}.
