Find the Quotient and Write in Rectangular Form A) $\frac { \sqrt { 2 } } { 2 } + \frac { \sqrt { 2 } } { 2 } \mathrm { i }$

question 32

Multiple Choice

Find the quotient and write in rectangular form. First convert the numerator and denominator to trigonometric form.
- $\frac { \sqrt { 3 } \left( \cos \frac { 7 \pi } { 4 } + i \sin \frac { 7 \pi } { 4 } \right) } { \sqrt { 6 } \left( \cos \frac { 9 \pi } { 4 } + i \sin \frac { 9 \pi } { 4 } \right) }$

• A) \(\frac { \sqrt { 2 } } { 2 } + \frac { \sqrt { 2 } } { 2 } \mathrm { i }\)
• B) \(- \frac { \sqrt { 2 } } { 2 } - \frac { \sqrt { 2 } } { 2 } i\)
• C) \(- \frac { \sqrt { 2 } } { 2 } \mathrm { i }\)
• D) \(\frac { \sqrt { 2 } } { 2 }\)

A reinforcement schedule that reinforces a response at unpredictable time intervals, leading to steady, moderate response rates.

Reinforcement

In behavioral psychology, it refers to any stimulus which strengthens or increases the probability of a specific response.

Contingency Responding

A learning process where the learner adjusts behaviors based on the presence of specific stimuli and the consequences that follow those behaviors.

Instrumental Conditioning

A learning process in which behavior is modified through the use of rewards or punishments.
