Answer:
3, 6, 9
Step-by-step explanation:
To find the first 3 terms , substitute n = 1, 2, 3 into the n th term rule.
a₁ = 3(1) = 3
a₂ = 3(2) = 6
a₃ = 3(3) = 9
Answer:
(1) . -11
Step-by-step explanation:
f(-2)=-3(-2)^2+
-12+1=-11
2/33 is the answer to the question
The relation between the secant and tangent is used to prove the equation. The detailed description is given below.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The equation is given below.
tan⁵ x = tan ³ x sec² x - tan³ x
Taking tan ³ x common then we have
tan⁵ x = tan ³ x (sec² x - 1)
We know that sec² x - 1 = tan² x, then we have
tan⁵ x = tan ³ x (tan² x)
tan⁵ x = tan⁵ x
Hence proved
