2. TOPICS COMPLEX NUMBERS VECTORS MATRICES

3. COMPLEX NUMBERS  Change mode or setup to complex Press ‘mode’ or ‘setup’ Select ‘CMPLX’ i.e. Press ‘2’  Activate complex mode Press ‘shift’ and then ‘2’ Displays complex operations

4. COMPLEX NUMBERS Inputting complex numbers:  Cartesian form: x + yi a + bi  Polar form: rcos + irsin r <

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

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

7. VECTORS  Change mode or setup to vector Press ‘mode’ or ‘setup’ Select ‘VECTOR’ i.e. Press ‘8’  Activate vector mode Press ‘shift’ and then ‘5’ Displays vector operations

8. VECTORS Inputting vectors:  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.  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.

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

10. MATRICES  Change mode or setup to matrix Press ‘mode’ or ‘setup’ Select ‘MATRIX’ i.e. Press ‘6’  Activate matrix mode Press ‘shift’ and then ‘4’ Displays matrix operations

11. MATRICES Inputting matrices:  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.  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.

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

13. 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.
