Answer:
Sin (270º)= -1
Cos (270º) = 0
Tan (270º) = -∞
Sin (330º) = -0.5
Cos (330º) = = 0.8660
Tan (330º) = - = -0.57735
Step-by-step explanation:
The sum of the infinite geometric series is -288.
<h2>Given that</h2>A finite geometric series with n = 4, a₁ = -144, and r = ½.
<h3>We have to determine</h3>What is the sum of the infinite geometric series?
<h3>According to the question</h3>The sum of the infinite is determined by the following formula;
A finite geometric series with n = 4, a₁ = -144, and r = ½.
Substitute all the values in the formula;
Therefore,
The sum of the infinite geometric series is,
Hence, the sum of the infinite geometric series is -288.
