A number 4 times as much as 25 is 100
Answer:
D. 1
Step-by-step explanation:
We have the expression,
We get, eliminating the cosecant function,
As, sinx is reciprocal of cosecx and cosx is reciprocal of secx,
i.e.
i.e.
Since, we know that,
Thus,
So, after simplifying, we get that the result is 1.
Hence, option D is correct.
Answer:
(tan(theta)-1)^3
= (tan(theta)-1)(tan(theta)-1)(tan(theta)-1)
= (tan^2(theta)-2tan(theta)+1)(tan(theta)-1)
= tan^3(theta)-2tan^2(theta)+tan(theta)-tan^2(theta)+2tan(theta)-1
= tan^3(theta)-3tan^2(theta)+3tan(theta)-1
