Explanation

The ways in which Nigeria has demonstrated that Africa is the centre-piece of her foreign policy are:

(i) Support for OAU: Successive Nigerian governments have given political, financial and diplomatic support to the Organisation of Africa Unity because Nigeria believes that OAU is the foremost continental machinery for the articulation of African interests.

(ii) Nigeria's African policy is shown in her anti-colonial pre-occupations as Nigeria has committed herself to ridding Africa of all forms of colonialism and neo-colonialism by sending aid and material assistance to freedom fighters.

(iii) Nigeria identified herself with the anti-apartheid front by giving moral, political, financial, material and diplomatic support to the liberation movement in South Africa.

(iv) Nigeria has often undertaken the promotion of intra-African economic co-operation, e.g. creation of ECOWAS in 1975 and the African Economic community in 1991.

(v) Nigeria is committed to peaceful settlement of inter-state disputes as she has played active role in the settlement of political crises in Liberia and Sierra Leone through the formation of ECOMOG.

(vi) Nigeria has.been seriously involved in the promotion of intra-African sporting competitions through hosting of important sporting events, e.g. the All African Games and the African Nations cup co-hosted by Nigeria and Ghana.

(vii)Nigeria has championed the provision of technical aid and expertise to sister African States, e.g. TACS.

(viii)Nigeria has shown high commitment to the promotion of cultural ties amongst African nations, e.g. FESTAC.

Explanation

p = 8cos30i + 8sin30j

q = 9cos150i + 9sin150j

p = 6.9282i + 4j

q = -7.7942i + 4.5j

pq = (-7.7942 - 6.9282)i + (4.5 - 4)j

pq = -14.7224i + 0.5j

|pq| = √((-14.7224)2 + (0.5)2)

|pq| = √(216.7491 + 0.25)

|pq| = √216.9991

|pq| = 14.7309

the unit vector in the direction of p - q = \(\frac{-14.7224i+0.5j}{14.7309}\)

-0.9994i + 0.0339j ? -i + 0.0339j
