a. Explanation Given: The vectors r ( t ) and r ′ ( t ) are parallel for all values of t in the domain. Counter example: Let assume r ( t ) = 〈 cos t , sin t 〉 . The derivative r ( t ) = 〈 cos t , sin t 〉 is computed as follows, r ′ ( t ) = d d t ( r ( t ) ) = d d t r ( t ) = 〈 cos t , sin t 〉 = 〈 − sin t , cos t 〉 The derivative of vector r ( t ) = 〈 cos t , sin t 〉 is 〈 − sin t , cos t 〉 b. To determine The statement is true or not. c. To determine The statement is true or not.

⚫ your circuit diagrams for your basic bricks, such as AND, OR, XOR gates and 1 bit multiplexers, ⚫ your circuit diagrams for your extended full adder, designed in Section 1 and ⚫ your circuit diagrams for your 8-bit arithmetical-logical unit, designed in Section 2. 1 An Extended Full Adder In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…
