<span> by taking integral we get
integral sec(x) (tan(x)+sec(x)) dx
applying integral we get
sec(x) (tan(x)+sec(x)) gives sec^2(x)+tan(x) sec(x)
= integral (sec^2(x)+tan(x) sec(x)) dx
Integrate the sum term by term
= integral sec^2(x) dx+ integral tan(x) sec(x) dx
For the integrand tan(x) sec(x), now we will use substitution
substitute u = sec(x) and du = tan(x) sec(x) dx
= integral 1 du+ integral sec^2(x) dx
The integral of sec^2(x) is tan(x)
= integral 1 du+tan(x)
The integral of 1 is u
= u+tan(x)+constant
Substitute the value of u which is equal to
= sec(x):
so our conclusion is
:tan(x)+sec(x)+constant
hope this helps</span>
Answer:
the answer is option D
Step-by-step explanation:
if you add the no of students in favour of the survey
32+42+58+64=192
which makes the first option incorrect.
The opinion of tenth and eleventh graders are not identical.
11th and 12th graders gave a favourable response
so options A,B and C are incorrect
Answer:
Triangle AEC
Step-by-step explanation:
Triangle ABD seems to be congruent to triangle AEC, because AD looks like it's equal to AC, AB looks like it's equal to AE, and BD looks like it's equal to EC, satisfying the criteria for an SSS congruence. Of course you could also go by the angles for SAS, SAS or AAS.
