Answer:
Step-by-step explanation:
Factor each half of the expression separately:
Since both 4k² and 7 are being multiplied by (7k-6), we can combine them to get:
Answer:
3 is the correct answer...
3 tan³ t(theta) = tan t(theta)
3 tan³ t - tan t = 0
tan t ( 3 tan² t - 1 ) = 0
tan t = 0
t 1 = k π , k ∈ Z
3 tan ² t - 1 = 0
3 tan ² t = 1
tan ² t = 1/3
tan t = +/- √3/3
t 2 = π / 6 + k π
t 3 = - π / 6 + k π , k ∈ Z
A) the only mistake is changing the mixed number to an improper fraction .
That’s the answer to your question.
