Perform the indicated operations. Express results in polar form. See Example 3. 15.9 142.6 18.5 71.4
Question:
Perform the indicated operations. Express results in polar form. See Example 3.
15.9∠142.6° − 18.5∠71.4°
Data from Example 3
Perform the addition 1.563∠37.56° + 3.827∠146.23°. In order to do this addition, we must change each number to rectangular form:
Converting back to polar form, we get 3.641∠122.24° (see Fig. 12.17).
Transcribed Image Text:
1.563/37.56° +3.827/146.23⁰ = 1.563(cos 37.56° + jsin 37.56°) +3.827(cos 146.23° + jsin 146.23°) = 1.2390 +0.9528j 3.1813 + 2.1273j = -1.9423 + 3.0801j -

As an online math tutor, I have several years of hands-on experience working with students of all ages and skill levels. I hold a Bachelor's degree in Mathematics and a Master's degree in Education. Additionally, I have completed multiple training courses in online teaching and tutoring methods.
Throughout my career, I have worked with students in both individual and group settings, including classroom teaching, after-school tutoring, and online instruction. I am proficient in teaching a wide range of math topics, from basic arithmetic to advanced calculus and statistics.
One of my greatest strengths as a tutor is my ability to adapt my teaching style to meet the unique needs and learning styles of each individual student. I understand that every student is different, and I strive to create a comfortable and supportive learning environment that encourages growth and development.
In addition to my formal education and tutoring experience, I am also a lifelong learner with a passion for mathematics. I am constantly seeking out new resources and methods to improve my own knowledge and skills, and I believe this passion and enthusiasm helps to inspire my students as well.
Overall, my hands-on experience and proficiency as a math tutor are grounded in a combination of formal education, practical experience, and a genuine love of mathematics. I am confident in my ability to help students achieve their goals and succeed in math, and I look forward to the opportunity to work with new students and continue to grow as an educator.
