TOPICS �COMPLEX NUMBERS �VECTORS �MATRICES

COMPLEX NUMBERS ØChange mode or setup to complex • Press ‘mode’ or ‘setup’ • Select ‘CMPLX’ i. e. Press ‘ 2’ ØActivate complex mode • Press ‘shift’ and then ‘ 2’ • Displays complex operations

COMPLEX NUMBERS Inputting complex numbers: Ø Cartesian form: • x + yi • a + bi Ø Polar form: • rcosᴓ + irsinᴓ • r<ᴓ

COMPLEX NUMBERS Changing from cartesian to polar form: Ø Input complex number in cartesian form then press ‘shift , 2’ and then ‘ 3 , =‘ Ø Input complex number in polar form then press ‘shift , 2’ and then ‘ 4 , =‘

COMPLEX NUMBERS Argument: Ø Press ‘shift , 2’ and then ‘ 1’. Now enter the complex number in any form and press ‘=‘ Conjugate: Ø Press ‘shift , 2’ and then ‘ 2’. Now enter the complex number in any form and press ‘=‘

VECTORS ØChange mode or setup to vector • Press ‘mode’ or ‘setup’ • Select ‘VECTOR’ i. e. Press ‘ 8’ ØActivate vector mode • Press ‘shift’ and then ‘ 5’ • Displays vector operations

VECTORS Inputting vectors: Ø Press ‘shift , 5’ then select dimension(Dim) and then choose any vector A, B or C. Also select whether its 2 dimensional or 3 and then input the values. Ø Press ‘shift , 5’ then select data(Data) and then choose any vector A, B or C. Also select whether its 2 dimensional or 3 and then input the values.

VECTORS �Performing calculations: �Recall the vectors by pressing ‘shift , 5’ and then ‘ 3’ for Vct. A ‘ 4’ for Vct. B and ‘ 5’ for Vct. C �For dot product recall first vector then press ‘shift , 5’ and then ‘ 7’ to input the dot and finally recall the second vector �Vct. Ans is like Ans its to recall the last calculation result you got between your vectors.

MATRICES ØChange mode or setup to matrix • Press ‘mode’ or ‘setup’ • Select ‘MATRIX’ i. e. Press ‘ 6’ ØActivate matrix mode • Press ‘shift’ and then ‘ 4’ • Displays matrix operations

MATRICES Inputting matrices: Ø Press ‘shift , 4’ then select dimension(Dim) and then choose any matrix A, B or C. Also select its dimensions(no of rows x no of columns) and then input the values. Ø Press ‘shift , 4’ then select data(Data) and then choose any matrix A, B or C. Also select its dimensions(no of rows x no of columns) and then input the values.

MATRICES �Performing calculations: �Recall the matrices by pressing ‘shift , 4’ and then ‘ 3’ for Mat. A ‘ 4’ for Mat. B and ‘ 5’ for Mat. C �You can add subtract multiply. etc. �Mat. Ans is also like Ans its to recall the last calculation result you got between your matrices.

MATRICES �Determinant and Transpose: �For determinant press ‘shift , 4’ and then ‘ 7’. Now recall the matrix whose determinant you want to find. �For transpose press ‘shift , 4’ and then ‘ 8’. Now recall the matrix whose determinant you want to find.
